That is good to know about online checkin. We have not seen any of the evening shows as my kids were very little last time we were there. Which ones would you recommend?
It's hard to make a recommendation as a lot of these shows resonate differently with people. You may want to sneak peak some youtube videos to help make a decision.
MK - Happily Ever After: Brand New Fireworks at Magic Kingdom - synched with projections on the castle, almost a consensus don't miss show!
DHS - Fantasmic: Classic nighttime show with lots of songs from the older Disney animated movies - one of my favorites but some say it's dated
DHS - Star Wars Spectacular: Fireworks with lots of projections - if you aren't into Star Wars probably not high on the list. If you are it may be at the top of your list
AK - Rivers of Light: Never seen it - looks neat but not as good as the 3 above IMO - others may feel differently
EPCOT - IllumiNations: not my cup of tea...but some people say it's the best show of them all
If you want to see Happily Ever After you have to go to MK on a non-party night. There's a lot of schools of thought on how to pick parks (some of which contradict others)
- Avoid Extra Magic Hours Park (and some people vary this rule to say only avoid evening EMH park)
- Avoid Party days at MK due to early closure
- Go to MK on party days due to early closure (yes - direct opposition to the statement above)
- Avoid MK and EPCOT on Saturdays because they are crazy
- AK and DHS are half day parks
- AK and DHS are full day parks (lol)
- Don't go to the same park on back to back days because it gets boring/repetitive
- Avoid MK on Mondays because many people go there on the first day of a weeklong vacation
- Go to AK on Sundays because it's usually the least busy park that day
....and these tips go on and on....good luck! I came up with about 6 scenarios for your days and wasn't really crazy about any of them.
