We will be at WDW the same week as you. For us, May 11-19.
We'll be there on my MIL's b-day.
I've made an ADR for dinner at LTT.
My MIL said she wanted to have dinner with Mickey. Mickey's not at this character meal, but Minnie is, - close enough!! (We'll be dining with Mickey on other evenings).
We will get her a b-day button to wear in the parks that day. I'm hoping she'll wear it.
I'm going to call the Main Street bakery when it gets closer to our trip & order a b-day cake to be delivered to the restaurant for our dinner that night. There'll be 8 of us in our group...2 are my kids, so we do a lot of character meals.
Make your ADRs soon, although if you are a just a party of 2, you should have an easier time booking now, rather than if you were a larger group.
