ITALIAN FESTIVAL BOUTIQUE CAMPING

I run a luxury camping company and I need to work out how much space I have in an area and give my client a plan - my computer needs updating to install SketchUp so I thought I'd see how much it would be for someone else to do it! Attached are: - The ground area I have to work with (within the red lines). - A screenshot of a bell tent in plan to get the shape right including the door so it is clear which way the tents are facing. - My very rough sketch of how it may look although the curved shape of the land with restrict tents to the bottom right side. I need to fit 75 of these bell tents in the area allowing space for walkways and WCs and Showers. All the tents are 5 metres and can sit 6 metres from middle of door to next one middle of door. The top row needs to allow a 4 m walkway between the boundary line and tent door. Each double row of tents will sit back to back but staggered slotting into each other to create more space. Between each double row will be a 2 metre access walkway. I think (!) it is relatively straightforward until it comes to the curved section and it's a question of working out how to fit the remaining tents in there (leaving space for WCs and Showers - this should ideally be about 15m x 10m. It is tight I think but doable. Anyone want to help?! There may well be more work :) TIMEFRAME: by tomorrow midday
