I just returned from Houston jast night. I stayed in Conroe near family so didn't have much for choices , but stayed at the Baymont ( first time ever for this brand) Clean, comfortable with all the conveniences ( dorm size fridge, microwave, free breakfast etc.) for $75 night.
That being said, I had a wonderful surprise when I stayed the last night at the Holiday Inn Express airport on Will Clayton PKwy. Wanted something close to airport as I had an early flight
Started with a beautiful lobby, and wound up with a great King Suite ( a real suite, not a bedroom with a couch) Really! check this one out. Rate about $105 per night. This is regular rate, not a special. This room was as nice as many of the upscale hotels. I have stayed in.You won't regret this choice, if you can stay in this area.
