We visited MK on April 29, with two teenage girls. Although we were staying off site, we managed to do everything we were planning to do, and a bit more!!! We had Genie+, and we made plenty use of it (we booked a total of 6 lightning lanes); of course, I had personally done a lot of research as to which attractions to book first. The fact is that we arrived at the park at around 8,20 am (the park officially opened at 9) and we left for a break at around 1 pm: from 9am to 1 pm, we did a total of 7 attractions (2 of them with Genie +). In the afternoon, we came back at around 5,30 pm and did a total of 8 attractions (4 of them with Genie+). At 9 pm, we were ready for Enchantment, the fireworks: this was a rather chaotic moment at the park, and we found it really hard to find not a good place, but just a spot to be able to see something.
All in all, we enjoyed our day at the park, which also included plenty of pictures (we bought Magic Maker, and we found it very convenient). It's true that some rides tend to have problems and stop working from time to time, something that happens not only in MK, but in the four Disney parks.
