All three hotels are close to each other and located on Soi 6, which is a calm soi contrary to e.g. Soi 4 or even Sukhumvit road. I was only in Citrus Suites. Citrus Suites is a good value, guest and LB friendly, no hassle hotel. The restaurant downstairs is shit (go eating somewhere else). Book a larger room  - one bedroom executive suite - it is worth it. Ask for a room with non-leaking shower. No balcony, so if you smoke, you must go downstairs outside. The pool on the top floor is OK, standard measures for Bangkok. A German friend of mine was in Park Royal and was satisfied. The pool is downstairs and always in the shade. All rooms have a balcony. It underwent a renovation some five years ago. Its name was different before the renovation. Dynasty Grande was  long time closed for renovation. AFAIK, there are no balconies. I have no other infor on this hotel.

Agoda skips taxes and fees to make the price look lower. Be aware of the total.

google

Agoda do have good price , but I find once you find the hotel you like do a google search on it and google will show you a list of price and often the price listing on google is cheaper then search under Agoda for the same hotel Example: GOOGLE - AGODA - $100 Search inside AGODA - $110  

I am arriving September 21st for 4 nights.   They are all roughly the same price…10k Baht all in.   I do not eat breakfast, watch TV, shop, or sightsee.   I plan to spend my 4 nights walking between CIB10, WN04, Chaos, and possibly OB.   I will expect to bring 1 girl a night back with me after midnight for st.   Any feedback or will either of them do the trick?   I did think it would be cool to try and hang out at the pool one day with a new friend…kind of eliminates the Park.     Sent from my iPhone using Tapatalk
