Instead of trying to just get mine free, I talked it over with a couple of friends and we split the cost of 3 rooms among our families. So instead of one family getting in for free and 2 paying 99.95, we'll each pay 66.67 ... this allows everyone to get a good deal.
Sure I know everyone wants something free, but now we get to hang out with 2 other families this way and the kids will have a much better time with a larger group too.
We won't be going until early June though. We've never been there before. Hoping DH will hang out with kids and I can squeeze in an appointment at the spa. We hope to hit Gurnee Mills after we check out since I haven't been there in years.
