Convenient but Mixed Experience: My son and I stayed at All Towne Suites while attending my younger son's Army National Guard family day and graduation. The location was very convenient—only about 20 minutes from the base—and the hotel was clean, quiet, and overall pleasant. When I arrived early (around 12:30 PM), I asked about early check-in since the standard time was 3 PM. I was told there would be an early check-in fee so I chose to wait. The receptionist said he might be able to check me in between 2:30 and 2:45pm. However it was frustrating to see another guest walk in around 2:30 and get checked in right away, even though I had been waiting nearly two hours. When I finally checked in the first room smelled strongly of smoke. Thankfully the receptionist was understanding and quickly moved me to another room which was much better. Although the hotel met our needs and had a great location the customer service experience left me unsure if I would return. Still it served its purpose for our short stay.
