L.D.
When my son turned 1, we rented several of those ride toys like you used to see outside the grocery stores. One was a rocket and the other was a car (both of them had seats like in a cart and had seatbelts). These worked great for all the children. An adult sat next to each ride and instead of puting in quarters, we just clicked the trigger to start it. We had fruit smoothies and angel food cake with blended strawberries and low fat whipped cream so the kids wouldn't get wild and hyper. I believe you can also rent the inflatables, but with the weather so cold, that might not work well. The rides we got fit in my in-law's enclosed sun porch.
