I don't think there's any way around it since the below is what is said on their website... If I were you, I'd just be sure to call on the very first day that they're open for bookings. Thank you to all our guests for another incredible season! See you next year! 2020 Season Dates: Open: Monday, April 20, 2020 Close: Monday, October 5, 2020 Important Dates to Remember and Mark your Calendars: – Wednesday, April 15th: Phone lines reopen! Call to book your 2020 summer reservations!
It would be difficult. Most sites were booked one year in advance. I was there for July 2019 and 2020 were fully booked. It doesn't hurt to call and check on their reservation status because from time to time people cancel and sites open up. However, only time they take calls are during the time and hours they posted on their website, no exceptions. Good Luck!
Just be sure and call the first day. That's the only way for reservations.
