I'll go the opposite of the previous poster. Lol. We have young kids and for the reason, I love hoppers. My older DD4 loves the characters. Always has. We typically meet 30ish or so each visit, and half of those we see multiple times, like Mickey and Minnie. This last trip, she was determined to meet Sophia for the first time. I bought her and her little sister, 2, matching Sophia costumes as a surprise. Well, we spent an hour at the art of Animation waiting for Sophia. She danced with Jake for about half that time, but it was Sophia she wanted to really meet. We finally found out Sophia wouldn't be coming. So, I talked them both into wearing the costumes again the next day just to get a picture, then change to new costumes (they are big on their costumes!) afterwards. That was to be our DL day, but we popped over to CA mid morning to meet Sophia. Success! (And one of my favorite memories and best picture of the whole trip!) We also popped over when my DD4 wanted to see Viva Navidad a second time, then found out it was cancelled due to weather, so we tried again the next day. Also switched to meet Stitch at the Visa meet and greet. On our CA day, our DD2 wasn't enjoying the rides as much, so I hopped over to DL with her to go on some of her favorites. I love the flexibility of hopping. Maybe it takes a bit of time (15 minutes?) but it's worth it to not have to worry if we miss something- we can always just go back to do that one thing. We also switch for food, too, depending on what the kids feel like eating. DL can get crowded, so we like being able to move to CA in the evening when DL gets hectic. At WDW, I'm good without hoppers. At DLR, it's a must for us.
