I do understand the frustration but what the card owners are doing is maximizing their ROI for the cards they aquired. Some specifically purcahsed cards for the purpose of renting them out. Makes sense they would want to get max ROI in return to pay for the card they purchased.

Currently contracts are for 24 hours only and nothing over that is gntd. When the renter selects multi day renting its not gntd that card will be available for those days. The gntd time frame is 24 hours. That being said, I'd like to see 24 hour / 3 day and 7 day rental contracts. While 3 & 7 day contracts might not give the best ROI it will likely garner the card owners a loyal customers. I'd happily choose the three or even seven day option to lock in my rented cards.
