You may bring anything from the bar down to the beach, you just have to tell the bartender you are doing that, because glass bottles and glasses are not allowed. The lapu lapu is served in a pineapple, so no problem with glass there!
The movies are on the beach in view of the fireworks, so you won't have to move at all. I'm not sure if the Wishes soundtrack is piped through the movie speakers or not (they pause the movie for the fireworks if the times overlap), but you will want to ask that question. If not, make sure you scope out a place on the beach from where you can hear the background hawaiian ambience music...the soundtrack to the fireworks plays out of the speakers. I'm not sure if you're technically supposed to watch the movie on the beach if you are not a guest at the resort, but I have never heard of anyone ever being asked to leave. Especially if you are a guest of 'Ohana and are buying smores kits. I would think that after dinner at 'Ohana, one package would be plenty for 4, since you will just want a taste.
I believe that the times of the movie are seasonal, so you will have to check what time the movie is showing the week you are there.
At 'Ohana, there is a price for adults and a price for children 9 and under. It is the same whether you eat everything or close to nothing. They will bring out an alternate meal if you don't like what they serve. Last time we were there, we saw adults eating grilled cheese. That's a hefty price to pay for grilled cheese, but to each his/her own!
Upgraded to concierge, and we are thrilled! We are having a magical time! 
-it has helped me very much.x.
I'm just so excited. We normally stay at POP or CBR so this is a real treat.
