I would make them soon. Over shoot on the estimate for the number of people just in case you have others who want to join in later. If they limit the number of people in your party, we can always call in secondary reservations to cover the other people.
I seem to have secret powers over CMs to get them to condense several reservations into one.
Anything listed on the park maps as an attraction is fair game for inclusion in the Rally.
I cannot confirm nor deny the inclusion of any attraction in the Rally.
Mamabot and two kids (right? I am going to be embarrassed if I am wrong)
Sadako (squeee! I can't wait to meet you!)
Dustysage- are you bringing Fishbulb? I would love to meet him!
Crazy Legs (another squee here!)
