Couldn’t take advantage of double night promo due to family commitments so I wonder if AGU HP is cool with 30 night stay but I have no intention to stay beyond 1 or 2 night. I assume they see a lot of Hyatt mattress runners? If not then probably do some nights in dfw or iah or my PIT airport HP.
Not being there for days on end risks confusion. . . .and getting checked out by mistake. If you go that way make sure the hotel understands the plan and consents to it. Some do. Some maybe not. Less risk of misunderstanding is shorter multiple stays where you come and go. But your call.
