I'm absolutely gutted... took the van in for a 6 month service today and the garage have discovered that both nearside springs are snapped

What's particularly gutting is that we're meant to be going away for a few days tomorrow

So what I would like are your opinions as to what I should do...
A - have a miserable few days at home and then sleep in a cardboard box at work while the garage have the van next week to get it ready for V
B- drive very carefully and not overload the van but go away anyway, do work as normal and then pray to the Van God that the mechs can repair it on Thursday next week ready to go away to V on Friday.
C - another solution???
Any advice would be much welcomed

Also - how much time (in work hours) should a garage be taking to fix this as they are quoting me 6-8 hours which seems a bit extreme?
