Because the type of room (2-bedroom suite) is not available on Hyatt points for the night I need. And...if the event I need the room for gets cancelled I don't want to have points in Hyatt - I would want them in my URs.Why not transfer the ur to hyatt? Is it less ur to book than transfering?
Thinking I may still use URs. $100 is less OOP than the $300+ they want for the room if I don't use points.
