I know most recommend staying on-site for the early entry and front of the line pass.. but for economical reasons would staying off-site and buying an express pass for 2 adults and 2 children be worth it? Our main purpose for our mid-March visit is to see WWOHP. We plan on traveling 03/17/2011 - 03/03/21/2011. HELP!!! I need to make reservations ASAP. If this helps we are AAA members.
