Planned on staying after a late night return flight and parked my car at hotel upon departure. Was able to get an earlier return flight and thus did not need room, so cancelled a day in advance (during my trip). Received cancellation number from agent - no problem. Upon returning to hotel to pay for parking ($5 per day = $10, but they charged me $15) was RUDELY told by desk agent Eric that I was wrong and would have to pay for night anyway. Charged my card and abruptly dismissed me.
Hotel manager - when I called later to request a refund rudely scanned/emailed the parking contract and said "if you park, you have to stay a night". Fine, I'll pay, but I'll NEVER use another La Quinta again.
From what I was able to see the property was sloppy, bathrooms dirty, breakfast area musty. Don't bother - there are PLENTY of other good properties near the CLT Airport.
