You'll be in the parks which is exciting in and of itself.
On our last trip, we spent a week at WDW, with 4 park days, and didn't advance schedule any dining reservations or fast passes at all. We'd wake up, decide which park we wanted to go to, and on the way to the park, we'd schedule fast passes and maybe a TS meal. We ended up eating at Tusker House, San Angel Inn, 50's Primetime, Hollywood & Vine, and Cape May Cafe. The only rides we didn't ride were Navi River Journey (line way too long for a boat ride), or Seven Dwarves Mine Train (did it once on a prior trip...lines were too long without a fast pass this time).
It's always a great time at Disney (though this last trip was the least fun since we stayed on-site and we prefer off site).
