When you arrive before check in time.....

[purple figment]

We are concerned about leaving iPads, deodorant etc in the car in July heat.

You can check in any time after 6 AM, although your room might not be ready until later. You can leave your things with bell services. Once you are in your room, you can call bell services to deliver your luggage. We've left our carryons including electronics with bell services and never had a problem, but if you are concerned about the safety of the ipads or any other items every resort has safety deposit boxes (like those at the bank) behind the check in desk that you can use.
