Assuming 7nights = 7 park days for you...
7n No Hopping = 4 MK days with wishes + 3 Other Park Days
5n With Hopping = 5 Park Days with wishes.
So by cutting 2 days off you would get a max of 5 nights of wishes but 2 whole days less at the World.
By cutting park hopping, you can still get 4 nights of Wishes, thus 4 MK days and still have 3 other days for AK, DHS, Epcot. Plus with 4 MK days, you could have some down time on those days.
Personally i would rather have more days at the world, but that's just me.
Along the same lines as this post, if you are going in October there will be 3 or 4 nights that MK will close early for MNSSHP, so you won't be able to watch Wishes those nights. I would skip the park hopper option this time if I were you. We're going the last week of September into October and 4 nights are MNSSHP nights. We decided not to get park hoppers this time, in order to save the $300.




I thought that's what the OP was asking for.
, i misunderstood that part from the OP, my bad.
DW and I have gone on vacations before where one of us had an issue with the destination, plans, etc. and it ended up not being very fun. So now we both have to have total buy-in or we just don't go.
