Kona is wonderful for dinner. We will probably have dinner there on our first night but I haven't made a PS. If the plane is late, luggage takes long, etc., I don't want to worry about missing the PS.
When you check in, it would be easy to walk up and make a PS at that point. The checkin CM may be able to make it for you as well. I know they can check on PSs but not sure if they can make one too? You could also call as soon as you get to your room.
Sometimes Kona gets very busy for dinner but if you have a PS made even shortly before you dine, you should be all right. Of course, maybe it won't be busy when you arrive and you won't need one at all.
If we're really tired, we'll do room service. Room service at the Polynesian has wonderful burgers...tons better than B&C IMHO.
We check into the Polynesian 5 days after you. Have a great vacation. I can't wait.
