Decided to go Pattaya for 2D holiday. Only been here once, so this is still perspective from a newbie.
Agogo Bars
A must-see for newbies going Pattaya. Drinks are cheaper than BKK's Soi Cowboy or Nana, and there are so many options for agogo bars all in one location. Got special shows like girls in Jacuzzi, girl on girl, some S&M (Iron club) etc. Girls wise, Bacarra still beats the rest, but there are some gems in the smaller agogo bars. BF and ST/LT rates varies between bars, but generally the BF is 600B and ST/LT are 2K/4K.
Soi 6
Never been here before, and it was interesting to walk down the street. Mostly MILFs and tanned skin ladies, so may not suit everyone's taste. Kawaii bar had the better looking girls along the soi

This is just my humble opinion. Maybe can find gems in other bars, but I didn't really go in and seat down. It was just based on glancing at the girls while walking past.
MP
If you've been to BKK MPs, it's not worth going to the MPs here. Honey 2 had the most number of girls when I visited, and the prices quotes was 2-3K. Not sure if this is tourist price or standard price. But the quality of girls really CMI, maybe 1-2 gems for the highest range. Even the fishtank girls costing less than 2K in BKK beats the girls in pattaya anytime.
Hollywood
Totally different from the dead Hollywood in BKK. This place was happening, even during a weekday. Was told that it gets packed on Fri and Sat. The best part is there are Free Lance girls paid by Hollywood to work there (as I've been told), and they are there to keep single guys company. Can also do ST for 3K. There were some quite pretty ones available for company. Normally they will hang around at the back near the entrance, either waiting to be called to go meet guys through the service staff or mamasan, or they will mingle with the crowd. Can be hard to differentiate the working girls with other girls who are there for fun (either themselves or with male company). Can always tip the service staff to ask them bring girls over for company. No wonder that this place is popular with the Asian group. Didn't see many angmohs there.
Best advise is to stay at either end; near walking street, or closer to Big C where Hollywood, MPs, Soi 6 are within walking distance. Can easily hop on to Song Kaew bus to travel around. Made the mistake of staying outside this area, cost like 200B to book a Song Kaew to send me back late at night. It was raining and didn't want to take the walk, hop on song kaew, take motosai...
