Good, but sad info. Seeing the Dolphin is still using Double beds that seemed to make sense on the category differences, I wonder/wish/hope they would change to Queen beds.
I'll toss this bit in there too....
Beginning February 11, 2018, SPG is changing its booking window. Previously, the SPG program allowed members to book their future stay a maximum of 550 days in advance, but as of February 11, the program is aligning itself with Marriott and only allowing booking (paid or award) 350 days in advance. If you already have a reservation, it will not be affected by this policy.
