Planning on going to Bangkok/Pattaya this December and I like this hotel in Bangkok "Carlton Hotel Bangkok Sukhumvit" because it's new, the rates are good and it allows a third person for a fee. This is the link to the agoda listing https://www.agoda.com/en-gb/carlton-hotel-bangkok-sukhumvit-h10231638/hotel/bangkok-th.html
The question is how do I know if they are a guest friendly hotel or not? I googled it and did not find them listed on any Guest friendly lists. But that might be because they opened in 2019.
I know I have to book the room for 2 adults.
