Does the UMP (I think that is what it is called) need to be for the entire length of stay? We will be there for 6 days, but most likely only go to the parks for 4.
Also, can we get the UMP for other guests staying w/ us that are not DVC members?
They always let you leave off one day--arrival or departure day--upon request. Often they will let you leave off both those days but that is hotel discretion at the time. You can buy the passes at the discount rate for guests staying with you.
