Do I need a visa for a 2-week holiday in Thailand in May?

It's your first time in Thailand ?

What a stupid question, sorry

No

UK has visa exemption for 60 days. You will have to fill out the new online arrival card 3 days prior to arrival though (at least 3 days before arrival, but access isn't available until the 28th of April i think)

if your American, there turning them back at the airport at 77 countries lol its called the new Trump visa

Please find attached bus time table to Pattaya

There's this new thing called Google, it's really awesome you should check it, you can actually get answers for questions instantly, cool concept huh? Thinking about investing in Google but don't know if it's going to last lol

Starting by activation on April 28th 2025, the filling out of the TDAC online form becomes mandatory for all foreigners who wish to enter Thailand

This includes expats who are holding valid stay permits who are returning from a trip abroad.

You should prepare all the information that is needed to fill out the TDAC, in the "Notices" folder of your phone.

Like passport number, date of issue, issued by whom, date of birth, your full name, the address in Thailand, etc. By being prepared, you can just copy and paste it into the TDAC online form.

It takes 5 minutes max to fill out and submit

Then wait for the email confirmation. Print it or keep it in the “notices” folder of your smartphone

Not if you are from Warwickshire and have a British passport.

Depends on what country you’re from if you’re an American then no

What is your passport origin?

That depends on what passport you have, which you have not included in your post so we have no way to tell you if you need one or not.
