Tammy,
We had an early check in too, they gave us a pager to let us know when our room was ready. In the mean time they told us where a hospitality room was, so if we wanted to change and use the pool etc....we could.
As for the free breakfast, you won't have any problem, no tickets are needed for that...........everyone just goes and gets breakfast.
I'm sure you will have a great time, it's a great place to stay.
Kim
