Children aged 2,5 and 7.

Please give me your Super terrific suggestions of places to visit in:

San Francisco

San Diego

LA

New York

Hawaii

Thanks to you!!

San Francisco - Pier 39 to see the sea lions. A ride on the cable car. Ghiradelli Square.

San Diego - San Diego Zoo, Sea World

L.A. - Disneyland, Santa Monica Pier

New York City - American Museum of Natural History, Children's Museum of Manhattan, The Brooklyn Children Museum, Children's Museum of the Arts, Liberty Science Center, Central Park Zoo, Bronx Zoo, Central Park Carousel, FAO Schwartz, Disney Store.

Hawaii - which island?

Hawaii... the beach? Seriously I'm not sure what kids could possibly enjoy more than that!!!

Rome (too many sites to list!)

Paris, hands down.

London (lots of parks, activities for the kids, free museums with kiddie activities)

Switzerland (in summer. lots of green space, cable cars/trains, cows, cheese and chocolates)

Bali, Thailand--Hua Hin (choose a nice hotel with beaches and pools, good amenities around, kids-friendly staff, interesting culture)

Monterey Bay Aquarium

San Francisco - Pier 39, walk across the Golden Gate Bridge, Golden Gate Park and the Academy of Sciences, Alcatraz (and/or ferry or boat cruise). Other than the chocolate, I don't think kids that young will be as excited with Ghiradelli Square - it's mostly upscale shops. Pier 39 is more kid friendly.
