Can I check in early?

Rhey let me check in early every time.

Call them, it's dependant on the day's bookings

Yes

You can check in whenever you'd like. They may or may not have a room available, just depends upon the day, but if they do, you'll likely be let in early

You can do a pre-check-in before 3, they will give you a temporary key that gives access to gym and pool. They'll then email you when your room is ready.

Yes you can check in and even leave your luggage(they have a secure storage room big enough for both my Segways and several others) until your room is ready. Sit by the pool or outside bar or have a meal in the restaurant while you wait.

Yes, but no earlier than 3 pm
