We’re coming on 01/10-16 with our two boys- 3yrs and 19 months old. Staying at Great Wolf Lodge, but wanting to get out and do other things. Zoo was at the top of our list, but concerned that the weather will make it too cold to enjoy, and keep animals from being active? Thoughts? Also, suggestions for things to do around there with that age group? Restaurant recommendations, neat shops, just general ideas for what to do, Thanks!
