Zion and Las Vegas don't need any explaining. Harmon's Grocery has really good deals that even beat Walmart from what I saw (5 for $20 on meats). Check them out as they are really friendly and worth the stop. For a sandwhich shop, check out Even Stevens. For every sandwich ordered they donate one to the local shelters and you can watch the number change as people order food. Really cool.

hope this helps out.

Zion is a MUST, it is beautiful, just wonderfully amazing. Install the REI (Hiking project) apps to your phone and check out the best hikes. If you are intense about hiking you will not be disappointed, try Angels Landing, the Overlook. the App is wonderful, it give you details of the main points elevation difficulty, what to expect and time it takes. It's the best App I've used so far and it's FREE. Difficult and daredevil hikes include Angels Landing, you can check out YouTube videos, but don't be scared by them, the daredevil part is only at the last 0.5 mile and you don't have to do it. Hubby and fam did I did NOT. Observation point 6+ miles round trip, Do the Narrows, lots of water. There are easy one, it's just an amazing National Park
Enjoy
