Rope drop is definitely crazy...if your MIL has never used an
ECV it can be kind of intimidating. I would suggest if you are going to do it that you hang out in the back and just take your time letting the crowd feed through before going in, which really defeats the purpose of RD. You could also try and snag a PPO breakfast or do the extra magic hours thing that they are offering now (although not sure how long that will be around)...that way you won't have to deal with all the craziness of RD but still get to be in the park at RD.
