What days in July? If you will be there for the 4th, take them over to the Grand Floridian to see the fireworks on the grassy ledge by the lake. You can stop in the snack room there and pick up some desserts to eat while you enjoy the wait.
I personally think it is more important to show newbies, especially the sceptical ones, the "other side" of Disney that most people miss. Most sceptics think that all there is at Disney is crowds and rides.
If there are kids on your trip, take them to Fort Wilderness to the night time campfire movie. My kids also love the Contemporary arcade. I personally love to sit out by the pool at Wilderness Lodge with a glass of wine, cheese and grapes (for sale in the snack shop too) while watching the gysers go off by the lake. Parasailing is a blast and unexpected on a Disney trip.
I could go on and on, my point is to show them the unexpected.
