Looking into camping as well. There are free camp sites (and paid showers) there and also a campfire hopefully, (however, National Parks are testy in this area, so if no fires are allowed this will make a difference).
6+ hrs of riding in one day is more than Terese is happy with at this stage, so an overnighter is on the cards. Probably cold at that time of year tho and might end up coming myself and returning on the day.
Seems like lots of options at this stage. Tentatively, Terese and I will both be there.
