Report UPDATE: San Marcos 2023 Embassy Suites Room Block... in About the IPMS/USA National Convention Posted August 11 20 hours ago, jcorley said: Mike, that just means that the non-block rooms are gone or on hold for special rewards members. I checked the hotel website a couple of days ago, and it also showed sold out, but as a Hilton Diamond member, it would let me go ahead and book a room. . . for $880/night. I'll wait for the block to open up, thanks.
