No, dont expect it to be slow. Our very first MVMCP was the first one of the year, and I thought it was crowded. We still had fun, and the park looked beautiful. but it was definately not slow.
We will be at the Nov 29th one for sure.. and we are considering going to the first one too!! HAve fun!!
If I can make a suggestion, get to the park by 6pm. Last year for the first MVMCP of the season we arrived at 7 and it was very crowded getting in. The year before we arrived by 4:30 because we had CP ressies so we were already in when it began.
