We have experimented with floors. Last year we used my wicker trays as floors. This year I had laminated pieces cut to size. But, they really aren't sturdy enough. I will have to go back to plywood next year.
I use two of his generals from his fort set as doormen. We bought wooden furniture one year when the blocks kept tumbling down.
We let the boys control the speed of the train. At one point the engine disengaged and went roaring away. The excitement built as it came full circle and crashed. No damage done, but it was fun to watch. Every hotel is unique from year to year. I loved adding more boys to the mixture. I hope it continues as a family tradition.
