You were asking if there are any European ladies available. I've done several CR trips for the past few years and will be doing another one in May. I have yet to see any true European or Asian women working the Gulch. There have been a few girls who "look" European or Asian but all the follow up posts I've read on CRT say that they are, at best, of mixed race but still essentially Chicas/Ticas.
If European or Asian is your true interest, I think you'll have to consider a trip to a different continent to truly enjoy those pleasures. I hope to do an Asian continent trip myself in a few years. Realistically, I would advise you to consider the women of CR exclusively as a Central/South American experience.
Personally, I'm planning to check out Relax, New Fantasy and HLH for the MP experiences and hanging out at the HDR, KL, and SL for my more "meaningful" relationships.

To me, GFE and PSE are about as meaningful as I plan to get, with maybe a few TLNs to make some of the mornings a little more interesting. I did the BangBang 57 tour last year and I might explore that avenue if the other MPs don't measure up.
As some of the other members suggest, get out of the box (or bed) and see what else CR has to offer. I'm a city boy and my first time ever going deep sea fishing, whitewater rafting, ATVing, and canopy were all with my buddies in CR. We also visited beaches, saw extinct and active volcanos, and enjoyed the hot spings of Arenal. Great experiences and a whole lot of fun!
These field trips are not only a lot of fun, they allow you to re-charge your batteries, too. Even just going out shopping or exploring downtown and finding some shops to buy a few gifts and finding some local restaurants to enjoy a good meal adds to your trip. Unless, of course, you're like a few select members of CRT who seem to have two gallons of leche stored up inside and can pop a nut 8-10 times a day. In that case, I'd just stay at the HLH and have the girls line up outside my door and do'em in pairs, threesomes, and more. But for the rest of us mortals, an occasional field trip or a stroll around downtown is a great way to both reload the pistol and also enjoy some of the other excellent activities CR has to offer.
