Alright Gabe, you're added!
Dates are set, as no one chimed in as having a conflict and some have already asked off.
If we get a beach house for the week, we can split it so that it works in everyone's benefit. Total price of house divided by # of days = per day cost. The per day cost will be split per the number of people staying that day. If we can only get a house in a one week block, and we're just interested in an extended weekend (say Thursday-Sunday) we'll make calculation adjustments.
I'll start looking for houses to accomodate the number of bedrooms needed. I'n most cases these houses have a lower playroom (pool table, TV, etc.), so maybe some of the kids can have a slumber party downstairs. Then the adults can have some adult beverage time.
In any case, I'll post up the house particulars before booking it.
