maximum post dated delivery to an airport is 10 days + transit time, or 7 days to other addresses + transit time.

you can post date deliver your bags to hotel #1 for day 7, then post date it to another hotel for day ~14. Finally send them to the airport for another 7 days. this is a lot cheaper than airport storage at 800/day.
