I would make a PS for as early as possible for a couple reasons. When we stayed at AKL and ate there, it was a busy place each night. Even though we had a PS, we had to wait about 20 min. to get our table and there was only two of us. Second, there is sooooo much wonderful food to enjoy! Even if you try a forkfull of everything, you will be stuffed like we were! We had a 6:30 PS and didn't start eating until just before 7. I had to do a bit of walking that night so that I felt somewhat comforatble beofre hitting the hay with a full tummy!
Boma is a spectacular experience for the eyes, nose, and taste buds! You will LOVE it!
