People of all ages travel internationally every day. The difference between traveling now when you're 29 and in the spring at 30 is negligible. I know you are disappointed but spring will be here before you know it. You'll still meet attractive girls at that age even girls in their 20's. My biggest concern is that you seem to have a vision of how it will be locked in and may get taken advantage of. Please be careful. You could ask your friend about his trip so you can get quality information as to what to do and what to avoid. You'll get there. Hang in there. Sending big hugs.
