I've stayed in Jomtien Palm Beach Hotel and have no complaints. It is reasonable, massive, huge rooms but it is an old hotel now so allow a little bit of a tired look. Has a bowling alley, massive fabulous swimming pool and great breakfast.
Main thing is it very close to the Jomtien Complex. It is a perfect location.
Another great peaceful hotel is the Agate Boutique hotel, right within the complex itself, looking out onto the bars. Great tropical oasis pool at the rear too. It's spot on.
As for the Andaz, it's way too far for the gay scene. And why waste money there on accomodation?......it's more expensive than the Hilton π₯΄
