I'd probably suggest splitting it $600/$400. If there are 5 rooms, pay $200 per room used. Or another way to look at it if I were to go on cost per person, I'd charge kids less as in that kind of scenario, I'm assuming the kids would have much smaller rooms. $150/adult, $100/kid. Family with 3 kids again pays $600, family with 1 kid pays $400.How in the blazes do you account for common costs?
Let's again say two families. Family one is using 3 bedrooms (parents and two kids bedrooms, total of 5 people). Family two is using two bedrooms (parents and one kids bedroom, total of 3 people). So there are eight people in the Villa using 5 bedrooms.
Let's say for the week, the rental cost is $1000. For me, it's simple, 1000/8 = 125pp. Family one pays $625 (125*5), Family two pays $375 (125*3).
The villa, in addition to the bedrooms has the following:
* Living room
* Eating Area
* Game room
* Private Pool
So, how do you split the cost? Do the age of the kids make a difference? A baby won't use the game room, but might make more of a mess.
If it were a standard 2 bedroom Villa at Disney with a couple staying in the king and a family with 2 kids in the 2 queens (not the living room), I'd think they should pay the same. A little more if the kids were to sleep in the living room.
