Key takeaways
- Plan the trip as a group: pick the big nights, build in rest days and agree a few ground rules.
- Heat makes hangovers harder, so water, shade and food matter more than any trick.
- Look after each other. Watch your drinks, travel home together and never leave a drunk friend alone.
- A drip is one option for the morning after, not a licence to overdo it.
A stag or hen trip to a tropical island is a brilliant way to celebrate. It can also mean several nights in a row of drinking in the heat, and a stag do hangover in Thailand can knock out half the group before the main event. A little planning keeps the fun going for everyone.

This guide is about the group: how to pace the trip, keep each other safe and recover well. It is not about drinking more, and the best weekends are the ones everyone remembers. The tips work just as well for a hen party, a bachelor party or any big group trip.
Why a stag do hangover in Thailand is different
At home, a stag or hen party is often one big night. On a trip abroad, it is usually several. Add long flights, jet lag, hot sun during the day and warm nights, and each hangover starts on top of the last one.

The heat is the part people underestimate. You sweat through the day and alcohol makes you pass more urine, so the group can be running low on fluids before the evening even starts. That is a recipe for headaches, nausea and very slow mornings.
A group hangover plan for the weekend
The person organising the trip can make a big difference by setting the shape of the weekend before anyone arrives.

- Pick one or two big nights. Make the others lighter, with an earlier finish and a few soft drinks in the mix.
- Plan rest mornings. Nothing booked before lunch after a big night.
- Schedule activities sensibly. Boat trips, diving and anything physical go before the big night, not the morning after.
- Build in food. A proper group meal before heading out helps everyone pace themselves.
- Sort transport home in advance. Agree how you will get back to your villa together.
For pacing on the night itself, and why scooters and swimming do not mix with drinking, read our guide to drinking alcohol in the heat. It covers those risks properly, so we will not repeat them here.
Hen party recovery in Thailand: simple habits that work
Whether it is a hen party or a stag weekend, the same habits make the biggest difference. None of them involve buying anything.

- Water between drinks. An easy group rule: one glass of water for every drink.
- Breakfast first. Water and something salty in the morning, then food as soon as you can face it.
- Shade in the middle of the day. A pool or a shady spot beats lying in full sun with a hangover.
- Sleep. A cool, dark room and a lie-in are worth more than any hangover hack.
- Oral rehydration salts. A sachet in water the next morning can help you rehydrate.
If someone in the group wakes up feeling rough, our guide to recovering from a hangover in Thailand has a full morning-after routine.
Koh Lanta tip: On Koh Lanta, Long Beach is the liveliest area for a night out, while the quieter west coast beaches are ideal for a slow recovery day the next morning.
Bachelor party hangover safety: look out for each other
The most important part of any group trip is that everyone gets home safely. A few ground rules agreed at the start take the awkwardness out of it later.

- Watch your drinks. Drink spiking happens in many countries. Do not leave drinks unattended, and do not accept drinks from strangers you did not see being poured.
- Know the signs. If a friend suddenly seems far drunker than they should be, very drowsy or confused, stay with them and get help.
- Nobody goes home alone. Leave together, or in pairs at least.
- Never leave a drunk friend alone. If they are drowsy, lie them on their side so they cannot choke if they vomit, and stay with them.
- Keep phones charged. Make sure someone knows the address of your villa.
Can an IV drip help the morning after?
Some groups like to have drips at the villa the morning after the big night. A drip will not undo the night before, but it can help you rehydrate quickly, particularly if you feel sick and cannot keep water down. Our honest guide on whether an IV drip helps a hangover sets out what to expect.
The Hangover Recovery drip contains 1 litre of saline, vitamin B complex and vitamin C, plus anti-nausea medicine and pain relief if they are suitable for you. Each person has their own health check with a registered nurse first, and the nurse may advise that a drip is not right for someone. If several of you are interested, our group bookings page explains how visits for a group work.

Rehydrate, settle your stomach and get your holiday back, without leaving your room. A registered nurse comes to your villa, hotel or bungalow anywhere on Koh Lanta.
When a hangover is something more serious
Most hangovers are miserable but pass with rest, water and time. Alcohol poisoning is different. It can happen when someone drinks a large amount quickly, which is more likely on drinking games and shots nights.

When to get medical help
Call 1669 (Thailand’s emergency ambulance number) or go to hospital straight away if someone is confused, cannot be woken, has a seizure, has slow or irregular breathing, has pale or blue-tinged skin, or keeps vomiting while drowsy. These are signs of alcohol poisoning. If you think a drink has been spiked, or something has gone wrong and you need the police, the tourist police number is 1155. Koh Lanta Hospital is near Lanta Old Town, and larger hospitals are in Krabi Town.
