For families with medical issues, the argument is even stronger. They need the break and vacation.
riggggggghhhht...
Someone has cancer so they need to go to a $10,000 a head program in Hawaii for Pesach...
Of course there are the programs for people who really need it, such as:
1) Single parent homes
2) Medical situation
3) People who just had a baby or some other occasion
4) People who just, as Dan wrote, want to spend Pesach together
Those programs are much cheaper, have a private seder option, are not in exotic locations, are in a simple hotel/convention hall, do not have top chefs and entertainers, and don't have unlimited food.
And most of these programs are doing fine. They have their clientele that comes every year and everyone is happy.
Its the gaudy ones that are the issue and are falling apart. Oh, and lets add some more reasons not to go to these:
7) The pritzus (the people or the area its situated in)
8 ) The kinah that it makes for those who don't go to these places and hear about it from their friends.
