It's hard to say what the discounts on CRO rooms will look like, but I'm sure there will be discounts. CRO is going to give you the maximum in flexibility. If you wanted to rent, I think finding a rental would be difficult if you don't already have it lined up. Inventory is super low right now. Availability in the 7 month window for the fall is pretty much non-existent.
On the rental front: IMO, I think that anyone who goes forward past this pandemic and pays a broker or anyone for a rental, upfront and in full, is crazy. What I've read are reports that many private owners did refund renters in full when they couldn't travel or rebooked for their renters due to the closures. Brokers have been all over the board. I think I also read that one broker allowed a rebook, but if this happens again, the renter will not be allowed to rebook again? And they are out their money? I know people would rather use a broker to rent, but really IMO finding a good owner to rent from is way better.
