Whilst dining at Kona in August, we ordered drinks at Tambu, then took them into Kona with us and the staff had no problems. I ordered the Malibu Macaw and subbed the Malibu for Peach Schnapps - it was very good! You could hardly taste the alcohol! I had no less than 4!
Lunch doesn't start until 12:00 at the Kona. We wanted lunch there on Monday, and were disappointed that we were too early. I had the Tonga Toast instead, which sure is good, but if I were going to have that many calories, I would have rather had it from one of the chocolate desserts, which were not available!
