I stayed at Le Meridien last week. The pool is lovely and quiet, with a very nice bar. (You can see the King Power Mahanakhon building - the one with the "glass tray" skywalk - from poolside.) They resumed the pool area renovations the last day or two of my stay, but it was no problem. Only a small part of the poolside area - maybe 10%? - was blocked off, although I guess that could have changed since I left.
