Well they will try and save the big Hotels , If you are on the city side you may be OK , but if you are on the other side it will have more problems ,

Really no one knows , and the few people who have the most information do not seem to be talking ,
This has been coming for weeks but the unlucky part is the high tides are at the same time so the downstream water has to battle the upstream tidal waters,

I cannot say what you should do, but if its going to cost you big money to cancel than just go and see what happens , I would say call the hotel and ask but Thais are not good at telling you bad news, so read between the lines of whatever they tell you.

On question may be where is the hotels generator , because if its in the basement and it floods there will be no power and you may have to climb the stairs.......

Let us know what you do.....
