Hi Dawsey, i stayed at Patong beach lodge Nov 2004. It is about a 5-10 minute walk to Bangla and the hotel itself is about 100m down a lane off Rat-u-thit. The pool was smallish, but it was still ok.
Im sure youve seen the rooms on their website, they are quite modern and clean but some of them on the smallish side. Maybe when you check in ask to see the room first, as my friends had a really large twin room with 2 beds, i had a good sized room with a double bed, and another friend had a small room.
No joiner fee, but not entirely guest friendly, and the guards and the desk staff always gave the disapproving looks but never said anything.
Good breakfast, and included in the room price of 785 baht for April if u book online (eg Directrooms)
Overall i would stay here again as it must be one of the best value hotels around patong during low season. If i had a TG staying with me i might choose somewhere a bit more girl friendly.
