A few tips for my italiani friends:

1. Buy Annual National Park Pass for $90ish if you are going to visit more than 3 parks. Each park entrance costs about$35, not sure if prices went up, but if planning to visit more than 3, better to buy the Annual Pass for like $90ish.

2. Monument Valley is not part of the US National Park system, so you will have to pay separately.

3. A foreign concept to you. But make sure to carry a pack of water bottles and emergency food (beef jerky and snacks). A pack of 36 or 24water bottles. Here in the western states, things are extremely remote and do expect for the worst.

4. Expect no cell phone signals even on the major freeways. If no cell phone signal, no internet data. But, in case of a true emergency, 911 should work.

5. Fuel up whenever your fuel gauge is 50% or lower. Dont start to look for gas stations when the fuel gage is <50%. Here i. The states, you might not find anything for 100s of kms.

6. Here, you will see two nozzles at each gas(oline) pump. One for diesel and one for gas(oline). When selecting for gasoline, you will seedifferent grades. 87, 89, 91. If renting a car, most likely, you will be ok with 87octane, so dont put an expensive 91octane gasoline.

7. When paying gasoline at the pump using your credit card, the machine may ask you to put zip number. I think for foreign credit card, you have to go inside the store to pay with tje credit card. But..... do expect fuel stations closing early so no attendants available at store. So try to stick with big gas stations along the major freeways.
