You can fly to Singapore early and just spend the day there - even the airport itself has gardens a luxury mall ((s) , cinema , showers , massage . No need to stay overnight . Singapore is expensive but lots to see in one day there if you choose to leave the airport
is it only the 2k fine or is this looked upon like an overstay. Different question Todd but my extension was done in Pattaya where I reside and I also reside in Bangkok where the owner just finally registered me. If I fly back to the mainland can I go to Bkk or does it have to be Pattaya?
