Can you get club level when renting dvc points?
No, you cannot get club level when staying at VGF whether it's by renting points or booking a cash reservation.
I am so sorry for your loss. I truly hope your trip brings your family some joy during such a difficult time.
I have stayed at Villas at the Grand Floridian, standard rooms at GF and GF club level. Honestly, I loved all of them. VGF has the most beautiful rooms on-property, IMHO. We have never rented points for DVC properties however as we do not like the non-refundable terms and conditions for rentals. I don't think you can go wrong with any of the rooms at GF, GF CL or VGF. I would suggest pricing out GF CL, a regular room at GF (we love the lagoon view rooms) and a villa at VGF. I do like CL, but I also like saving the money, staying in a regular room and then using the money saved for signature dining reservations and other special experiences like fireworks cruises, dessert parties, tours, etc. I would think about what other experiences might enjoy during your trip and seeing if those might be worth using the CL money on, instead.
