We spent three days/two nights on a Sun thru Tue over Presidents Day. Great value if you can avoid peak times, otherwise make sure to find a good package. Our kids (3 and 5) had a great time and the water park was appropriate for them for all except the solo tunnel slide (some stuff needed accompaniment by adults at thier age/height). The resort is set up to make it an easy experience. Arcade can get loud at busy times, and pricey, but still fun for the kids. Did not have a chance to try the onsite restaurant or the nearby faciliteis at the rest of Grand Geneva, but suspect that is a great option for the adults if the kids are self-sustaining age back at the room. Rooms are nice and set up well for bringing your own food. You get water park passes for each of the days you are there, including check in day and check out day (check out time is 11 am). So if you can get in your room early (check in time is 3 pm), you can get some good water park time for the kids. We avoided the last day as the hassle of packing up and being "transient" seemed difficult, although they do have changing areas and lockers. Probably easier in the summer.
