Just an fyi, we stayed at Poly for 1st time and had adr for Kona but cancelled. It is an open restaurant, not what I anticipated, and the area gets crowded with the spillover from those waiting for Ohana. Probably wouldn't be an issue for some or if you got a table in the rear. It was just something we weren't interested in so we cancelled the adr a few days before once we saw it. On the other hand, we tried The Wave and loved it. OP indicates there are teens in the group and I think it would appeal to them.
