Is there a shuttle schedule? Im looking at arriving at midnight and wish to ensure there will still be shuttle service that is prompt

You Will need to call the hotel and check

They run about every thirty minutes during the day. After hours, a call is required. Call as soon as you have your bags. If they are not there in 15 minutes, call again. I have had to call two or three times in the past. I have only stayed overnight once but I have parked my car there while flying at least a dozen times.

Believe so

Windham has a shuttle on demand. You tell them what time you need them and they will be there. They also allow you to park your vehicle onsite for a nominal price if you're not a guest.
