Registration for Texas Bear Round Up is off to a fast start. TBRU 18 takes place March 14-17.

As of 11 p.m. Thursday, only four rooms were left for Thursday through Saturday at the The Crowne Plaza, the host hotel, just two hours after registration began. The hotel is now sold out. Last year, TBRU took 36 hours to sell as many rooms. Organizers assure attendees there are plenty of rooms at the overflow hotels. The host hotel requires a minimum three-night stay.

Early registration ends Dec. 2 when the price goes from $98 to $120.

The overflow hotel is The Park in near Love Field on Mockingbird Lane, The Comfort in on Stemmons Freeway and the Hawthorne Suites on Brookriver Drive, a block from the Crowne Plaza. Shuttles are provided all weekend from the overflow hotels to the host hotel.

Among the Saturday excursions are a trip to South Fork Ranch and a newly added Choctaw Casino trip.

Last year the weekend raised $30,000 for area nonprofits including Youth First Texas, AIDS Interfaith Network and the Greg Dollgener Memorial AIDS Fund.
