I've had good luck with everyone getting a great spot/view. I always put my daughter in front of me so we can both see but only take up one railing spot and many people do the same. Having smaller or short kids - this is a great perk because they are almost guaranteed an unblocked view. We always ended up behind a kid on the shoulders down in the main throngs, so the cost is worth it to me, even at the new price. However, if we were going to MK multiple days, I would consider getting the FP+ instead on one of the days. But I can't bring myself to it with one MK day with only 3 FP+ and already 5-6 rides I feel you need one for to avoid crazy lines. Also I think this will phase out as a must do as the kiddo gets older/taller and can hold her own on the ground.
I've found the desserts hit or miss, but there is always something really yummy. Don't eat a late dinner for sure! And I am looking forward to the cheeses later this month since it's a nice offset to all the sweet.
