Registration is now open for this year's Sea Otter onsite camping spots. While the main site will not open for business until later this week, camping reservations have been opened for early registration. Judging by the look of the car/tent sites, about 60% of the spaces have been reserved by mid-day today. These car/tent sites are $240/3 nights or $320/4 nights. If you are looking to stay onsite this year, you should scoot over there and get a site before they're gone.
