I will!
I'm not a semi driver but there is a parking lot which is shared with the restaurant Denny's. There's more parking behind the hotel and on the side street. I've seen many semi's parked there. I suggest not to pull in at the entrance where Denny's is because it does not look like you will have enough turning room on a busy day. Not sure how secure it is and if they have security available. I'm sure if you inform the hotel you are parking there you will be okay.
Yes I believe security patrols the parking lots
