Hello Tracy,
I must confess to you that I always get a little weak in the knees when I think about dining at 'Ohana, specifically the bread pudding that is served for dessert. It is truly delicious!
Wishes at the
Magic Kingdom on 3/28/15 is currently scheduled at 10:00 PM (times are subject to change, however), and you can see them from both the restaurant and the resort's beach. However, I do want to alert you to some construction happening at the resort that could possibly impede your access to the beach or possibly block your views from the restaurant.
You may find it helpful to occasionally visit the website Tikiman Pages, which is an unofficial Polynesian Village Resort website. It contains photo updates of the construction, so you could follow the progress to be better aware of the status quo when you arrive.
Wishing you a magical trip; enjoy the bread pudding and the fireworks, too!
