How big does the area have to be?

We need about a 3 foot clear access route to get the castle into your garden - we may have to take it through on a sack truck due to some of the weights of our castles so please make sure there is room! It is not easy to push in through a house due to furniture, carpets, etc so please take this into consideration. Once in the garden/venue we need about 3 foot around all the sides for the electricity, blower, etc.
