How many parking spaces does an RV need at NRG Park?
At least two, and more for a canopy. NRG Park states that "RV's will need to purchase a minimum of two parking spots and need to park in designated RV areas in each lot. You will need to purchase additional spaces for canopies."
What to do about it
Budget the parking as a multiple rather than a single space, and add the canopy footprint separately if the activation includes one. The requirement is a minimum, so a longer unit may need more.
What it costs if you don't
Arriving having bought one space means either buying a second on the day if any remain, or not parking. A canopy erected over unpurchased space is a separate problem again.
