To add, I would never buy the Sheraton bedding (sheets, blanket, pillows). At least the crap they have at Vistana Villages and Vistana Resort in Orlando. The worst bedding ever. No fitted sheet and no duvet. The bottom sheet is a flat sheet, then for a blanket they use two flat sheets with a thing blanket in between. Complete garbage. We have started taking our own fitted sheet with us.
That said, we did just fork out over $500 for Marriott sheets, duvet and duvet cover for our king size bed at home.
