Grand Centre Point Terminal 21 also has nice views of the city on higher floors, also right next to the BTS station.

Site says its updated to June 2023 but who knows.

Best way is probably to see what hotel you'd like to stay at and then email to ask. Most will tell you straight up if they require a "joiner fee" or not.

While I've stayed here several times and can highly recommend it for being super convenient and girl friendly, I'm not sure that it would qualify for 4 or 5 stars - mostly due to the lack of services provided at that tier.  Overall though the room is great and spacious and the staff never bothered me.

I agree. Stayed here for my first trip. I'd say 3 star hotel but room was clean, staff was good and location is close to NP and the BTS station

I can recommend Adelphi Suites in Soi 8, very get friendly and easy to bring girls back

I can second this. Hotel is nice and clean and close to BTS and Nana Plaza. Has several food options and a 7-11 nearby. Also the Vasu exchange next to the BTS is also a great place to exchange currency with great rates.
