I've done several multiple rooms on one reservation and gotten extra elite stays and nights since Mar 2012. However, this scenario is mildly different. I need two rooms for the first 5 days and then only 1 room for the last two days after part of my party departs early. Can I book two separate reservations - one 5 day reservation and one 7 day reservation with my SPG on both and get stay credit for both or do they have to be on one reservation? Most of the chatter references "same reservation" for multiple rooms, but I'm wondering if any MPers have real world experience otherwise? If it has to be same reservation then I will book a 2 room res for 5 days and then a second res for 1 room for the last 2 days, but I just was more curious.
