I did the DDP on our last trip, and have it booked again for our next one, although I may cancel it. I considered the Deluxe Dining Plan but ruled it out. I have too many "credits" for the DDP, but not enough for the Deluxe.
The same thing happened last time. We ordered room service twice, and will do the same again. In my opinion that is a complete waste of 2 credits pp, combined with the fact that I order off the adult menu for my son with room service, so it made/makes more sense to pay out of pocket. I did the same with the Luau show. 2 credits for one meal that isn't double in price just doesn't make sense to me.
I also made the stupid mistake of not realizing that I COULD use 1 credit for H&V F! dinner package, so I paid out of pocket for that as well. Months later I realized (from a message board) that I could in fact have used the DDP for that meal. Oops.
Be careful of the "dining plan calculators". If you really want to get an accurate comparison then you need to go thru the actual menus and choose what you think you will eat. I've been too lazy to do this...and honestly, I'll probably never do it.lol My reasoning for possibly removing the DDP is because we do not need all of the deserts, I wish the 2 snack thing was applicable in 2016, but oh well.
