Okay..says it's based on 2 adults, 1 junior, 1 child...6 nights 7 day. and says from $58 which usually means value hotel value season and base tickets.
Pop Century $82/night. 6 nights at $82/night is 492. (548.58 with tax)
3 adult 7 day tickets, 1 kid 7 day ticket 803, (855.20 with tax)
Total = 1295 (1403.78)
per day per person (divide by 4 people, divide by 7 days) = 46.25 (50.14)
divide it by 6 instead of seven (number of nights in hotel instead of days in parks) and use the with tax figure the per day per person calculates to $58.49. So I think like often hapens they are just advertising their regular price in a different way to stir up interest making it seem as if it is a deal.
