so you want to get there at 7pm, and wait over 2hours for the fireworks, preventing others from eating? Honestly, in my opinion I think thats Rude. Not only are you affecting other people wait longer, your also killing your servers tips. O'Hana is usually a pretty fast meal, so like 45minutes. You waiting an extra hour and a half lets say is killing them for an extra 2 tips. Its just my opinion, but rude none the less to do. Keep your ADR at 8, ask for a MK view, and if you get it, great, eat your meal and enjoy. If your done, just walk to the beach and enjoy the show... Its just as good and doesnt ruin anyone elses experience..
