Do they have rooms for birthday parties

Yes

Yes, you would have to call them to discuss reservations.

Yes several. If you're looking for larger rooms they can accommodate various sizes

You can not have parties on the pool deck

I would think they do, but you will have to call and ask. They have big conference rooms. You might try the party on the third floor where the outside pool is. There is a bar on the first floor, maybe you could have it there.

Yes. There is a total of about 70,000 sq ft of meeting space, and they have suites as well
