There is a Groupon Getaway discount for Nickelodeon Suites. If you search Groupon Getaways you should be able to find it. $159 for a two-night stay for 6!
Yep, just getting on here to post the deal myself. Visit groupon.com for the deal. You can buy multiple groupons and use for up to a 10-day visit. Read the fine print for details on dates and blackouts, weekend night groupons cost more. But the week-day for $80/night sounded like a good deal to me. You will, however, still be charged the $25/night resort fee.
