th safari club is not a big convention, however the cheerleading convention is huge, and it is on at the same time. take DART, or a cab. everyone tries to drive to that place. the hotels in the area charge a fairly stiff price for overnight parking.
the outlying hotels will all be sold out. the kids cheerleading come in by the busloads, and need hotels on the cheap.
if you get a google map of the place, and then search hotels, you will be able to see all options. most hotels in dallas look alike. no character, very clean, decent breakfast buffet for 10-15. indoor pools are not common.
