Out of curiosity has anyone out there done any comparison of building footprint sizes between the different building sets. For instance I have just noticed after setting a tight piece of space up for a restroom from the DFW set I accidently tried to place a JW building set one and it didn't fit so I'm thinking such information may prove useful if people want to use as little space as possible for buildings in order to maximize space for dinosaurs. If no-one has and if there is an appetite for it I may have to spare time to test them myself.
