Just my two cents, but you may want to rethink this trip. Here's my reasoning. First, you are doing a hell of a lot of traveling in a short time. You have 15 stops over thirty days. Not even counting travel, you are only looking at two days per location. It looks like you're planning for one or two more locations, so you may even have less than that. Accounting for travel, your time per place drops to probably closer to 1.5 days. Second, given that you only have 1.5 days per place, your margin for error is very, very low. If only one flight isn't available, you're whole plan gets thrown out of whack. As others have indicated, getting a seat on certain flights may be easier said than done. Whatever you choose, have a great trip. Sounds like a trip of a lifetime.
