Well, depending on your familys budget, I'm not sure if some of these are possible, but I'll just list off the places my family likes to go;
City/Tourist spots;
Vienna - Austria
Prague - Czech Republic
New York City - New York
LA - California
Quiet/Relaxation;
Generally, we just go to the beach condo in Florida, but there's also these;
Hilton Head Island - South Carolina
Bahamas
Costa Rica
Singer Island - Florida
Camping;
Hayward - Wisconsin
Indiana Dunes - Indiana (no clue what the actual city is)
They're all fun places IMO, and I always suggest going to any of them if you can. [:
