If I make a reservation but later reduce it by a few nights (more than 120 days ahead of time), as long as I don't change my start date will I have any fees incurred? Will it effect my dining reservations? We are not sure if we will be renting points for part of the stay. I'd like to make the reservation now, then reduce it if our plans change. But we would know well in advance... 120 days or more.
