Hello fellow hikers and backpackers! I would like some help planning lodging and pre-Whitney activities.

I have plans for Whitney this September as an overnight trip with my husband and another hiking friend. We live in a place where my living room is 151' of elevation and I will need to spend a lot of time acclimating before Whitney. I know that there are campgrounds at 9000-10000 feet. I have found a website for the Rock Creek Resort at 9373 elevation, advertised as a good place for acclimating in comfort. Is it better to rent a car and stay there for several days or to rent a small RV and stay at a campground?

Or as an alternate, are there showers we can get to from the high altitude campgrounds if we tent?

From any of these we will be dayhiking at places like Cloud's Rest to enjoy and acclimate.

Any feedback and suggestions are most welcome!
