In an excited frenzy, we had a relative book a flight to join us at GHK for upcoming vacation. Only after did I call to check on adding a third adult. Booked with Gov't rate+DSU. Sounds like it's an additional $75 per night. Obviously I'm not going to charge the relative for my stupidity, but anyone have experience with this? Thinking I may just leave it off and deal with it at check-in. Won't try to hide our third person or anything, but thinking maybe I'll luck out at check in desk as Diamond and 4th time return guest (with plans for a 5th time return and wedding). If not, just comes out of Spa budget :-p
