We are going for a shortish trip for our tenth wedding anniversary with my kids, mom, and possibly my sister. We will have three full days, one nearly full day (day of arrival- expecting an early bedtime and have early dinner reservations), and one half day.

We are not buying park hopper tickets.

Is it worth it, in your opinion, to plan an entire day for the AK?
I see a few attractions the my DDs will be interested in but am not sure if my DS will be able to enjoy them (he may miss some height restrictions, I am going to measure him tomorrow).
Also, we have family passes to the Bronx Zoo and go fairly often. I am not sure if I want to spend a vacation day doing things similar to things they could do at home.

Any input is much appreciated!
