Hi everyone. My wife and I are flying to Coast Rica in June for 7 days and staying at an all-inclusive resort. Neither of us have ever flown before and obviously have never been to Costa Rica. We've been on two cruises where we went to Cozomel, Cayman Islands and Jamaica. My questions are regarding air travel and money. For starters how does baggage work? We have a layover in Houston, TX. Will the airline move our baggage from one plane to the other and is there a baggage fee? Secondly, we included a shuttle ride with our vacation package from the airport in Coast Rica to the resort which looks to be about an hour away. How will we know where to go and what shuttle to be on? And last, can I use US dollars and if not, how do you exchange it for Colons? Also, I had read somewhere that's it's best not to use credit cards and to get some sort of special ATM card?? I really appreciate any advice or tips! Thanks!
