possible? how much would that run me?
what about 2 chicas?
Slow down newbie. One will be plenty for you.

(Seriously, I would NOT recommend taking 2 chicas on a trip, that's double the chance that something goes wrong.)
It's all negotiable. Depending on the chica, you're looking at 100-300, plus all expenses (hotel, food, drinks, transportation, any activities). If she has young K*ds, she may need to get a sitter (another $30-40). I would not go any higher than $150 all-included (babysitter, etc) for 1 night.
Some will take $100 and see it as a "vacation". Others see it as lost opportunity for income and will ask for more. The more popular the chica, the more she will ask for generally.
DO NOT TAKE A CHICA YOU HAVE NO HISTORY WITH. It can be a complete nightmare if there's no "connection". If you had a couple sessions with somebody and she's cool, you could attempt it. Also, don't take somebody who doesn't speak English if your Spanish isn't good. You can only Phuck for so long, you'll need to be able to communicate at some point.
Keep in mind that these trip often go bad at some point, so you may want to have an exit strategy prepared. Put her ass on the first public bus to San Jose if things go south.
