You can try. Nobody, except the immigration officer, can say if you'll be allowed in.
Have you had any Covid extensions ever? Ever overstayed in LOS?
Were you ever on an education visa before??
Best to have the 3 proofs in any case:
hotel booking for a few days & onward travel reservation within the number of days you're allowed , & 20,000 thb or equivalent in $ Ā£ ā¬ in CASH is needed.
If your re-entry is on/after April 1, people may only be allowed 30 days...
You're on a lad's wee holiday, yeah? ; you're a tourist; yeah, you can enter again, just not wearing elephant pants or a shirt which says "same same but different" & you'll be fine, mate.
