Santa's Village was a very memorable part of my childhood - my mom's company had their annual company picnic there so we went at least once a year. Also, one of my best friends' (in junior high) dad managed the Polar Dome so we spent a lot of time ice skating and flirting with the boys at Racing Rapids.
My whole family just went to Santa's Village this past weekend and had a really, really great time. It brought back lots of memories for us and it was such a joy to share it with my kids (who are 2 & 5). The rides are perfect for their age. They did a great job restoring it - lots of pretty landscaping and everything has been freshly painted - it looks really good.
I would have paid the full price admission to go, but we were able to get the Groupon for 1/2 price for a family of 4, so that helped. I would say it's worth it to go once a year, at full price, and you are probably making the smart decision to wait until the end of the season to get the most for your money. Hopefully, they will be doing more with the food options, so to save some money and have a better snack or lunch, you can pack your own and bring it with you - the picnic grounds are free to use.
There are a lot of animals, and they do interactive shows with the kids to let them experience the animals, and the handlers walk around the park with the animals too. Even Santa was there the day we went and he was so charming. Lots of fun for sure.
