Ashley,
You are cracking me up, because you've managed to align your plans even closer to ours! So, I say you should choose the Garden Grill because - we have an ADR there at 6:05 PM on the 17th. Actually, though I haven't been to either restaurant I have heard LOTS of bad reveiws of Tutto Italia (though not universally bad), Garden Grill reviews are pretty mixed too, some love it, some hate it, but I think the rotating restaurant + the characters make this a great experience to go with little ones. Tutto is just Italian food. You can get that anywhere. (At least it's pretty darn common up here in the North.) Besides, this way we could have a little DIS meet, and when we run into each other the rest of the trip, we'll be able to say hi!
Because, we ALSO match up on these days:
Oct 17th - Epcot Day
Oct 19th - MK Day (HDDR for dinner for us, though)
Oct 20th - DHS until 5ish, but to Epcot for Le cellier!
Oct 21st -
MNSSHP! (won't be there until 4 pm though...)
Yeah, we might not see each other at all, but we could run into each other a lot. We met this one family at a previous stay at POFQ (not DISers). We were talking to them on the bus to MK one day. Later we saw them in line for Peter Pan, then again at Cosmic Rays. The NEXT day we were waiting in the holding area for the Little Mermaid @ DHS and turned around and they were right next to us, then we saw them a fourth time at Epcot. It was really funny that we kept matching parks, and being at the same place at the same time through no real planning...so it COULD happen.
Of course, maybe I'm giving you a good reason NOT to choose Garden Grill - avoid the crazy DISer and his slightly less crazy family.
