So many hotel rooms are meant to accomodate a family of 4, so you end up getting 2 rooms or a large suite instead of just a standard room. A lot of times museums, amusement parks, etc. will have "family value packs" of tickets or whatever and it's always 2 adults + 2 kids. If you need to rent a car at your travel destination you might be able to squeeze into a smaller car with a family of 4...but with 5+all your luggage you'll almost certainly need a minivan or large SUV, which will really add to the cost.
Sorry, that should have said "Travel expenses increase greatly from 2 to 3" not 4
