Voted 180/120. Why?
With the dining plan, it would be a feeding frenzy if it was less than 90 days. Add to that, the addition of free dining. At least if it's at 180 days, I stand a chance of getting the ADRs I need before the free dining is announced!!! Once free dining is offered, all bets are off.
I'm still tweaking my Oct ADRs. Started at the 180 day window. There is plenty of availability for that time of year. So, even if you book today, you are going to find ADRs for your trip....as long as you're more than a month out.
The system, as it is now, works. If you don't want to think that far ahead, you don't have to. You can book when you're ready....you just have to realize you may not get exactly what you want. So if you want something in particular, you need to book it as soon as you can.
My 180 day window, for my Oct trip, opened while I was on the Dream!!! I had no issue getting to AKL and booking my ADRs for my next trip. It was kinda fun, sitting there at my computer at Jambo House, making ADRs for 6 months later.
I do remember when the window was 60 days. Not too bad, but there was no regular dining plan at that time. Then, it went to 90 days. Still okay, but when the
ddp came along, there were a ton of people trying to book the same times at the same restaurants. It was crazy. I don't want to go back to that.
