I registered for this promotion and have already had one stay at the LV Hilton. I have an upcoming reservation for four nights at the Bethesda Doubletree. If I pay for the first and last nights with a Visa signature and the middle two nights with a Hilton Amex, would that count as two eligible stays with regards to the promotion? Or does it require that I check out sometime between the two VS nights? It'd be nice to get it over with.
Or, does anyone know if it's possible to make separate reservations but then have them be "merged" once I arrive and check in and not have to switch rooms each time but count as separate stays?
