We'll be going for around 28-35 days in Oct/Nov. Have 4 weeks booked now and just waiting to decide on doing the 5th week.
Annual passes for 3 is $1,550
Airfare out of Seattle is normally around $1,500
Food at around $100/day is about $3,000
Shopping is around $2,000-$3,000
DVC stay at BWV is 300 points and maybe another 100 points for that 5th week somewhere else. So say 400 points. MF on those points is under $2,400
So the total budget is about $10,450 - $11,450.
