“All the extra cost alot extra.”. Review of Great Wolf Lodge. First off, we purchased this during their '48 hour sale'. It cost $192.90 for one night in a standard room with 2 days of waterpark passes with 2 adults and 2 kids. From what I had read, this was a good price. We thought it was great to use the waterpark (1pm) before you could check in (4pm).
