I found dream teen to be expensive for what you can get in pattaya, honest. The girls are not super hot, but they do give a good massage. Asking 500baht for a bit extra up to 1500 EXTRA for complete service is crazy. Just go over to soi 6 and you can choosesomeone for the hour at 800-900 baht.
Want a girl to spend the night with you (otherwise known as long time) expect to spend about 1000-1500 baht to the girl + 600-800 baht for the bar fine. That is, if you know how to bargain
If they wont budge off 3000+baht, they don't actually want to go with you. There are tens of thousands of other girls, so never get your mind set on just one.
Also, sabai dee is my favorite. Last time I was there it was 1700 all inclusive, but they also have a small section with "higher end" girls at about 1900 or 2000 baht. Slightly lighter skin, less padding in the bras. You get good service in either area.
