Keep in mind that the clinic's stats are pretty much the same as stateside clinics. Sometimes first cycles work, sometimes they dont.
It took us five trips, four fresh donor cycles (plus an FET after cycle #3) in Zlin to get lucky and have our little guy who is now 13 months old. We were lucky too in that we again had three frozen embryos from our fourth donor, so went back over Thanksgiving to transfer our remaining embryos - surprisingly, it worked and we are now 26wks + with a little girl.
In all we made six trips to Zlin and loved every trip - even the ones resulting in BFNs. We used Zlin as our home base, and once we had had our appointments, we took off on the train. We have traveled quite a bit throughout the CR, as well as to Austria, Slovakia, and Hungary during our cycles. There are absolutely no regrets!
Not counting airfare/hotels/spending money (that varies for everyone) we spent less on our six transfers (four fresh donor cycles plus two FETs) than many spend on one cycle in the U.S. Something to think about in case it takes multiple cycles for you to get your family.
