I use SuperPark Garage right across the street from Hobby at least 3x a week. It is $4.99 a day, totally covered and I have never had a problem with break-ins/vandalism.

I've used SuperPark several times without issue. It will fill up around the bigger holidays so make a reservation for those times. Coupon here to get a free day if you stay more than 3.
