Closest hotel to the venue.
Camping area close to the venue. Cabins will likely already be full, but there are usually RV and tent spots available.
Gretna is considered "west Omaha" and has a few good hotels. This is probably the next closest you can find to the venue. It's near the interstate so getting downtown or to other tourist areas will be easy.
Not as close to the venue, but close to downtown and other fun areas. Still only a 30 minute drive to the venue!
