This may seem like a dumb question, but here's our situation. We are trying to decide between Disney or a beach vacation this year. If we do Disney, then we will likely stay at a moderate resort for the week. If we do the beach, then we would do one day at the Magic Kingdom and stay at a value resort for the night. Can I book a week at a resort, in case we choose the Disney vacation and also book just one night at a value resort in case we do the beach vacation and want to just do one day at Disney?
