For BWV standard view, member services suggests day by day for early December. I booked it that way the past 2 years after asking them what they thought. It's not that big of a deal. The first day they collect all the info, so it takes a little time (same as any other reservation), but after that you just say you want to add a night and you are off in less than a minute (once they answer). Tell them what you are doing the first day, give them your actual checkout day and when you call the rest of the days, they know what you want as soon as they pull up your account. They were very nice about it. You could wait until the last day, but you are taking a chance that some of your earlier nights will not be available. Dec 1 to 14 is very popular because of it being adventure season and there are not that many standard view rooms. I'll be doing the day by day starting Jan 5!
