Yes, the tunnel is very large. The park sites are hard to get & usually small, no hookkups. We always stay at Ruby's Inn just outside the entrance to Bryce. Full hookups and very large sites with a 'Campy' atmosphere. Ruby's complex has everything you'll need, even RV repair & gas across the street. Nice shops, resturants, motel if the DW get fedup. lol. Make sure to do the Navajo trail hike to the bottom of the hoodoos. AMAZING! Another GREAT camp is just west of Bryce on the hyway called Red Canyon Forest campground. Entrance is just pass the tunnel. Its my favorite in the west. Very large, well spaced, paved sites, modern pit toilets, but water only.
