Congrats on the trip!
July at WDW is hot and crowded. Drink lots of water! All quick service places will give you free cups of water. Some will give large drink cups of water. This is one of the best tips I follow during the hot months in WDW. We generally purchase the
DDP so I use my QS drink options as bottled water. If you don't mind carrying it around, bringing an insulted re-useable water bottle is good. They even sell straps to attach to them if your bottle doesn't have one.
Also wear plenty of sunscreen!
Take mid-day breaks if necessary...like go see the Hall of Presidents, the American Adventure or gift shops for example to get out of the heat.
I think those two tips are the best to keep in mind because if I'm hot and dehydrated I can get grumpy.
As far as WDW activities:
WISHES! WISHES! WISHES! This is a must do!! And be near the castle. Nothing like seeing Wishes explode right near the castle. Also nice is seeing Wishes from the Poly beach. Or from Nacrossee's at the GF - here they also play the Wishes music.
Fantasmic! I'd do the Fantasmic! dinner package during the busy summer months. Otherwise get there about and 1 to 1 1/2 hours early. Or go to the 2nd show if there's one.
If staying on property (which I recommend), go to the EMH to knock out the big ticket rides. We're usually pretty productive during the night EMHs with Expedition Everest, Soarin, Rock'n'Roller Coaster, Tower of Tower, etc. So if during the day these rides have long lines and or the Fast Passes are used up, we just wait til that park's night EMH to ride multiple times.
How long will you be there? That for me tends to dictate my activities. We're going for 12 days in August, so I'll probably make time for the water parks (especially since it's hot still!). Also our trip durations will influence our eating. If you have time might I suggest some table service places:
Le Cellier
Kona Cafe
Nacrossee's
'Ohana
Chef Mickey
Best of all make it your trip! Relax if you want to. Rush around like a commando if you want. Do character breakfasts. Get character pictures. And the most important tip I (try) to remember...WDW isn't going anywhere. So if I miss it this trip, I can see it next time.
