I just booked a trip for myself, wife, mother-in-law and two kids (1 y.o. & 3 y.o.) with two rooms (1 king & 1 double) for April 20 (4 nights).

The cancellation policy seems pretty relaxed: If your plans change please let us know – it’s free to cancel or update your reservation by 11:59pm local hotel time on Apr 13, 2018.

I have Diamond status, and looking forward to free breakfast at minimum. An upgrade would be awesome. I'll update after the trip.
