WDW for my parents 45th anniversary! Just the two of them😁

We've been to Disney more then I can count. My parents started taking me & my sister when we were little & we are in our 30's now. Now we're older we've added more kids & have a bigger family. My parents have NEVER gone by themselves (anywhere now that I'm thinking about it) but it's their 45th anniversary this year & they are FINALLY going, just the two of them in December 😊 I'm trying to come up with different things they can do. They always followed us kids & grandkids around to rides & ate where ever everyone else wanted. I'm wanting find some "off the beaten path" ideas for older people, places to eat outside of the parks like maybe at some resorts, shows & just whatever for my mom & dad😆
