Travelers ❤️ these 🏨 after their flight to San Antonio

Wyndham Garden San Antonio Airport Northeast
Everything was great except one thing. I got in after midnight and was needing to sleep in. However, previous guest set the alarm clock for 5:00 AM. So much for a good night’s sleep. You would think house keeping would check that. Would have been five stars if not for that.
