We're expecting to spend $200 on chalet and another $180-$200 on food the most.
so, ea person needs to pay only about $12.
the rest i'll fork out and sponsor.
we're expecting...say, 30ppl going for the chalet?
so 30 x $12 = $ 360.
the chalet will be probably on tue-thur. (lastweek of june hol)
BBQ probably on the 1st night.
