Anyone else having the number of guests in upcoming reservations randomly changed? There are only two of us and so far I'm up to three reservations (all at Marriott full-service hotels, all on points) where the guest count has increased to 3, 4 and even 6. It's not a problem unless you need to modify the reservation for any reason. You are immediately disqualified from some room types (e.g. one King) and the only way to fix the problem is to re-book at current - usually higher - rates. Once a total of 6 guests is reached (4 adults, 2 children) no re-booking options are offered. I remember a similar problem that could occur during the booking process but this is the first time I've had existing reservations - some made months ago - updated in this manner.
