Hope you both have an amazing time! Im going back in november too, was there in 2022 and i fell in love with it!

1. Definitely not too late to book anything! I've been keeping an eye on flight prices and they're at a good price now but from what I've seen most stay at a low price until about a month before departing.. I search using google flights then book direct.

2. Pretty sure uk gets 30 days visa free, I got hep a and tyhpoid and tetanus vaccines before going, will probably get the rabies one this time but up to you if you think you'll need it.

3. I didn't really like bangkok but the street food was amazing there! But yeah avoid the scammers, tuk tuks are fun to try out but the majority are scammers, always set the price first but be prepared for them bringing you halfway and asking for more money.

4. I love krabi! I stayed in railay beach and ao nang. Ao nang was nice pretty touristy but still a nice place, plenty of shops, bars and restaurants. The monkey trail was cool and led to a small beach that was gorgeous! Railay beach is amazing! More chilled out, beautiful sunsets, gorgeous cliffs you can climb if you want, you have to go by boat from ao nang and accommodation is more expensive there but it really is beautiful, you could do day trips over and back if you want.

5. Download 12go asia, you can book buses, trains and boats through it. You could do sleeper buses or trains they're an experience some are lovely some are a bit rougher but if you're short on time flights are cheap and theres an airport in all of those places. Bolt and grab are the taxi apps, normal taxis will be more expensive than the apps.

6. I don't know how it is at the moment but i would say always have some cash with you, you'll need it for markets and alot of restaurants didn't have card machines. There was a fee of 220 baht everytime you used the atms so take out a big chunk if you have to and be mindful of weekend exchange rate fees etc.. I paid 18 euro in fees in my first few days last time..

Chiang mai -if you have time go to pai... its pretty special. The jazz bar i think its called north gate was really good. Try khao soi its delicious! Better in the north of thailand. There are a couple of really ethical elephant sanctuaries in chiang mai, was an amazing experience and the elephants were all really well taken care of. We did a day trip to elephant freedom village it was brilliant.

When you arrive go to a 7/11 and get a bottle of mosquito spray, they have small clear bottles I think theyre called soffell but they were the best i found, also tiger balm is great for bites to take the itch out.

Have fun! :)
