I have used Comfort Inn's shuttle about 4 times as is. They are the closest to the airport so fast. The driver is great as well. Their hotel lot can be a little packed (after all its a hotel too). They have very low rates as well. However, this time I had a problem with the shuttle being on time. I was at the pickup zone at 8PM, but no driver. That could simply be because my watch was slow or I simply missed it. No biggie. But then 8:30 came and still no shuttle. I finally call to ask about the shuttle and they could only say they arent sure what happend cause a driver was coming back already from the airport. So basically I had to wait an hour, till 9PM, to get picked up.
