We were wondering what time check in is? If it's the usual 3pm, that doesn't leave much time for the water park, unless you stay the whole next day too.
You can get your waterpark passes before checkin. I think checkin is 3 or 4 but we went to the waterpark at 1. You can also use the waterpark the whole day after you checkout.
I don't recall for certain, but I'm sure the time is posted. That's the time at most hotels, but often, if a room is ready earlier, you can occupy it earlier, and the staff at Grand Harbor is a very pleasant group of people, ready to accommodate. Just call them and find out.
