Buying plane tickets was easy, but do not rent vehicles. Expect an additional$300+when you pick the vehicle up. We paid$375through hopper for a week rental and I thought it was fishy but the app said there would be$0due at pick up. We paid an additional$375 in fees(like$41concessions and$61adjustment tax fee), and warranty(no matter if you purchase one through Hopper) when we picked the car up. Extremely disappointed and would have been better off using enterprise app for rentals.
