Thanks for all the replies! I am currently in BKK (Park Plaza), just back from Ayutthaya, which is an awesome place!
I'm off in two days to Pak Chong, then I fly to Samui/Koh Tao for a week, then I spend another week relaxing in Lipe before I head back to Singapore!
Luckily I have booked my SIN-BKK segment with SQ, so I'll do a little bit of lounge-hopping like I did in BKK!
I'll write a trip report once I'm back
