I cannot tell you how grateful I am to the people that told me we would really want some type of stroller for Anna at Disney. She doesn't really ride in strollers much these days so we were thinking that we could get by with just an umbrella stroller for Owen. We would have seriously regretted that decision.
We weren't super stoked about buying yet another stroller, but the double that we have is way too bulky to travel with and is pretty difficult to steer. I don't even use it now because it's so heavy and barely fits in my trunk. I borrowed a double umbrella from a friend, but at the last minute (thanks Amazon Prime!) we decided to go ahead and buy a sit and stand of our own, knowing I'd get use out of it at the zoo now and in the future with #3. Kevin did a quick search for best reviewed double strollers and came up with the Joovy Caboose Tandem Stand-On. It's great.
We got it on sale too which was a real bonus. As a sidenote, there was a $60 price difference from one day to the next on specific colors. Today it's listed for WAY more than we bought it for. So, if you're thinking about making the purchase watch the prices for a few days. They'll probably change.
Kevin had to do a lot of folding it up, lifting it, and holding it on the bus rides to and from the park which wasn't super convenient, but I can't tell you how many times we said to each other, "I'm so glad we got this stroller." There were times that we wanted to get somewhere fast and we'd have Anna jump on so we could get moving. There were other times that she was just plain tired and would ask to ride for a while. And sometimes we'd have her ride just so we wouldn't lose her. It was much easier to maneuver through crowds of people with her on the stroller instead of dragging her along beside one of us by the hand.
