OP there's a lot of good advice on here but only you know what you like or can afford. It sounds like time is on your side because you will be in the area for a while. I don't have experience with LPIN but I have played in other places. A line up is difficult !
I literally didn't know what to do , the choice was impossible they were all so beautiful ! I would suggest you skip the line up at first and just hang out for a bit. Watch from the sideline LOL. I personally would love to have a sexy wing girl telling me about the girls and hanging out with me so that might be a good option.
Take your time unless money is not an issue LOL. You can burn through some serious cash if you aren't careful !
