Some hotels are known to be lb friendly, but is there really a guest friendly hotel that won't allow a lb guest? Can only think of one such place in Pattaya. It was one of the player hotels on or near walking street.
Could be off about that though, I do remember Nok mentioning some hotels wouldn't let her in.
I think the bigger worry is which hotel is going to charge you extra for a guest.
Lots of balconies in Pattaya.
In bkk I've received plenty of rooms that were supposedly smoke free, but had obviously been smoked in. Mariott and Majestic Grande for example. Last time in bkk I was at the Davis hotel with a russian who couldn't go 30mins without smoking, even worse since their windows are sealed, but only smoked in the bathroom and fortunately didn't get charged extra.
Executive 39 (I think the name was) had large room/balconies soi 39 but it's close to Darkside.
Phachara does have nice balconies, on the rooms with balconies, well most of them anyway, the deluxe suites balcony is nothing but an outdoor air conditioner stand. To make it more confusing some room types come with or without a balcony so you have to request it and hope they're not full.
