We did not get the dining plan for our trip last week and here are the reasons why we felt it didn't work for our family of four:
1) We never order four appetizers and four desserts (sometimes we split one appetizer and one dessert among the four of us)
2) We arrived late at our resort the first night and left very early on our last day-we didn't eat any meals at WDW either day
3) We wanted to eat at Rainforest Cafe at AK (family tradition) but it is not on the dining plan.
4) My 11-year-old still likes to eat off the children's menu (and most Disney restaurants still let her) but we would have to pay the full adult price for her under the dining plan. Our thirteen year old orders off the adult menu, but usually orders nothing more adventurous than a burger and fries.
5) My kids would much rather be riding rides than lingering over a three course meal, so although we usually eat TS at least once a day, we tend to eat at the more informal, less pricey places like Sci Fi
6) We like to be more flexible w/ our eating and snacking than the dining plan allows. For instance, we bought a huge tub of carmel corn at Sleepy Hollow to split among the four of us. It's a family favorite and we enjoyed it very much. Had we been on the dining plan, we could not have justified buying a snack that wasn't on the plan. We also enjoy buying refillable mugs to use at our resort and couldn't justify the extra expense had we been on the Dining Plan.
7) We saved $40 buying our park tickets from Ticketmania. We could not have bought our tickets from Ticketmania and selected the Dining Plan.
We ate what we wanted when we wanted last week, and there was only one day that we came close to spending what we would have spent per day on the dining plan. Of course, my family circumstances are very different from yours. If it was just my husband and me, we would probably enjoy going to some of the nicer restaurants and I think we could easily justify the cost of the Dining Plan.
Best wishes and have a great honeymoon!
