Which Disney park(s)? If you haven't already done so, download the My Disney Experience App and reserve your Fastpasses.
If the popular rides are sold out, keep refreshing. If you refresh enough, lots of new times and peeviously unavailable rides will pop back up for you. The easiest way to refresh is to just tap the Morning button (or any of the time slots), then check to see what's changed from there.
The ones to look our for are Seven Dwarves Mine Trains (MK), Flight of Passage (AK), Slinky Dog Dash (HS), and Frozen/Test Track (Epcot).
Also, the earlier you burn through your first 3 Fastpasses, the better, as you can then get one at a time back to back after each use for the rest of the day. Plan right, and you can Fastpass your way though all the rides.
Also, I'd highly prioritize Animal Kingdom. Both Pandora rides, the Kilimanjaro Safari, and Expedition Everest are my favorite attractions in the entire resort. Epcot's Food and Wine Festival is also great, but if you haven't already been to Disneyland or Magic Kingdom, MK takes priority.
Avoid Hollywood Studios. It's lame right now, a lot of it is under construction, and Toy Story Land is a letdown.
Typhoon Lagoon IMO is better than Blizzard Beach. They just opened Misadventure Falls last year, and it's pretty awesome.
As far as dining is concerned, I can recommend quick serve or sit down resrauresta for each park depending on your price range, too.
Have a blast, and let me know if you have any questions!
