I've been a single mom for 8 years and have made vacations a priority. We've fought the "baby swap" issue numerous times. Everyone is finally old enough (and tall enough) to ride everything (16,13,10) but when they were younger it was a challenge. My oldest son and I would baby swap so we would each ride. On occasion the CM would say "It has to be a parent", and I would go into my "Are you telling me you are going to discriminate against single parents? These are my children and my XX old son is responsible enough to stand here for the 5 minutes it is going to take. I resent that after paying for my tickets I am being deprived of the opportunity...." All of this spoken in a calm yet firm voice always got me on the ride, I never really made it past the first sentence. Often a CM would keep an eye on my children. Once the younger two reached an older age but were not tall enough or just didn't want to ride they would go in line with us and wait in the baby swap area or go to the exit area to wait while my oldest and I rode. The baby swaps are usually right beside the ride entrance. However the way we got my middle son to ride on roller coasters is we missed the baby swap on MGM's RRC (apparently it's at the beginning of the line) we got up to the front to get on and I found out we missed the area, they are moving the line along and I looked at him and said "you're riding". Luckily he loved it and from that point on we never had to worry about finding the baby swap. 2 years ago we rode 41 different roller coasters in 10 days, this year we are planning a west coast version. I've seen too many single moms not get out there and do things, where there is a will there is a way. I am adamant that we are a complete family and we will participate in everything. We've had some fabulous vacations, most theme park related!!
