I agree with Ftwildernessguy. It cant hurt to make the PS especially if you know what you want and that you will be in that area that day. Being a bit of a psychotic planner, I kow I would book it asap. With that said, we have eaten at Kona Cafe, quite a few times, for all 3 meals now, and for some strange reason it is never crowded. In fact DH always laughs at me and comments that hes so I glad I booked the PS, 90 days in advance(or 120 when it used to be that).

We actually did need a PS there once for dinner(on 12/28), but for the most part we find it to be fairly empty.
