We were there in July, and it was several years ago, so I cannot directly answer your question. If I remember correctly, we had a several-night reservation, which you would want. Our site was fairly large, albeit no services. What I can say is that spending time here is SO worth it, and if you can get on the boat that goes out on Crater Lake it is amazing. Be aware that to get to the boat requires a hefty hike in and out.

If you just reserve a site, you can avoid all the nonsense.

At Mazama Village they assign you your camp site - there is no choosing! If you booked more than two or three-night, this can be a problem. There are only a very few sites with power in section B and C. I saw large 5th wheels crammed into difficult and small site, and tiny teardrops in giant site - all assigned. It's a crap shoot! Our site was D1 where the picnic table, fire ring and Bear food locker was all on the wrong side of our trailer. So if you get any site with an odd numbered 1,3,5,7,9 and so on you will have the same issue. Only saving grace was the fact it was close to all the lake activities and the rim drive
