You would need a suite. Usually, at the deluxe hotels, the suites are more expensive than just getting 2 regular rooms.
Depending on the tickets you are buying look into upgrading two people to an annual pass for the room savings.
The unlimited express with the deluxe hotels is great, but with 6 people it might make more sense to stay off site in a rental with more space and private amenities and just purchase the lower tier one time express, especially if not everyone rides the thrill rides with the longest lines.
