No Owner shall rent his Lot for transient or hotel purposes, which, for the purposes of this Declaration shall be defined as either a rental for any period less than 30 days
Transient OR Hotel purposes. If you've got someone staying for a week, they are transient, regardless of whether or not you wish to have a concierge set up a card table out front to stand there and greet them when as they come and go.
A week is less than 30 days, no matter how many lawyer friends you care to consult till you find one who is willing to argue the point for a fee.
You agreed to abide by the rules when you purchased the property. You can't just decide the rules don't apply to you if you "Stand your ground"
