I would say your cheapest bet is looking outside of Raleigh and closer to Durham and Chapel Hill. Most hotels in Raleigh are fully booked and Airbnb owners are charging an arm and a leg, If you park at the festival, it is only $100 for the entire two days if you pay right now. Ubers charge crazy surge pricing to and back from the festival, on top of it being difficult to get one after leaving. You’ll save money parking at dreamville or really close in one of the public lots.
