Yes you can split your stay but it will require you to book 2 different packages.
For example 5 nights at . . . and 5 nights at . . .
This will also require you to put a $200 deposit down for each package.
The cancelation policy is full refund if canceled before 45 days out, you will lose $100 if you cancel before 6 days out and 5 days or less out you will lose $200 (for each package).
You won't be able to get there and then just switch resorts, you will have to book accordingly ahead of time.
