PokerinTheRear, for your stay in Bangkok it will be easy to find a reasonably priced hotel on Sukumvit Road - anything up to Soi 15 is easily walkable and on the even side up to Soi 12. A number of small hotels have recently renovated their rooms, which makes them a better value and place to stay than before.
As for the others - August Suites is a good choice and many have given it a good rating in the past. Is there any particular reason why you've booked 3 different hotels for your stay in Pattaya? Is that just for checking them out?
The usual strategy is to stay in one hotel (if you find you like it) for the duration of your visit, no need to spend time moving from one hotel to the next. In the end if you like all the hotels during your stay it will have been the right strategy.
Hope you have a fantastic time!
