When is the season opening for the 2018 season, days of the week, and operating hours? And what are the ticket prices?

If you buy a day pass after 2pm (or 3pm in summer),you also get the next day's admission included for free.

Opens memorial weekend, closes Columbus day. Weekends only in the shoulder season (june/sept) and every day late June-August. Ticket prices for that day are ~$35 but there are loads of deals - particularly on season passes which are often about the same as two day passes...
