Your ADRs look good, of the TS places you've listed, I've eaten at The Wave, Mama Melrose, and Le Cellier!
Ok, here is my rundown - You can't go wrong with anything at Le Cellier, although if you like mashed potatoes (I love mashed potatoes) and your meal DOESN'T come with mashed potatoes, you should think about subbing your side for them. They are wonderful! The Chedder Cheese Soup is yummy!
Mama Melrose - I would NOT recommend the fettuccine alfredo. It was kinda dry. My Dad swears to never eat there again. I, however, thought that the other meals looked and tasted good, especially the chicken parm. With a little more alfredo sauce, the fettuccine would have been good too. (I think Dad was just in a bad mood that day, it is just unfortunately one of the things I remember).
The Wave - I was afraid (as were several of the waitstaff members) that Disney missed the mark with this one. From what I've seen of the menu on allears.net, however, it seems they have changed the menu up a bit. I don't know, I typically don't think that when I go on vacation I want to really think about eating healthy food, and everything on the menu when we went was very much geared toward that. We did ask for pancakes with regular pancake batter and they were happy to oblige. I have no complaints about the food that I ate when I was there, simply about the limited selection.
We are planning on eating at Boma and Teppan Edo while we are there in December, so I am counting on hearing your reviews, if you decide to go there for ADRs!
Sunshine Seasons is great for a CS, there are so many different selections to choose from, even the pickiest eaters can find something they want. If you've been reading Meg's (autumnpalm) TR, she has some really nice things to say about Tangierine Cafe, and that looks really yummy!
I don't really know much about the CS at DTD, but House of Blues has good food, and a fun atmosphere! It's a sit down restaurant though, or I know we sat down and ate there.
Looks good!! Good luck with getting everything you want!
