Our first family DVC trip is scheduled from Jan. 3-Jan 10th. Recently I found out this was during the Marathon week-end. We have reservations for a grand villa at BLT for the entire week . I recently found out that some of our party will be leaving on the 8th. What I would like to know is what kind of crowds are we looking at because of the marathon? Will it be difficult to switch to either a 1-bedroom or a studio for the 8th and 9th of Jan?We will not know the exact number that will be staying for the full week until July 7th. Thanks for any help or information you can give me on this.
