Except this year (2015) there is a convergence of President's Week and Mardi Gras at the same time which will definitely bump up the crowds. This happened in 2007 when we were there, we really felt the crowds jumping exponentially as we approached President's Week. We did try to factor in an increase in crowds for the end of our trip in our plans, and thought we were prepared, but even though I use to pride myself as a planner, those days just before President's Week were overwhelming. Forewarned is forearmed!
