Since both reduakari and pygathrix referenced my upcoming 8 week road trip, I feel compelled to reply. My wife and I are definitely not rich, but simply enjoy spending a good chunk of our saved cash on holidays. If we were to ever win the lottery then we'd probably never stop travelling!
@reduakari: the Bronx Zoo is regarded as arguably the best zoo out of the 216 AZA-accredited establishments in North America, perhaps slightly ahead of San Diego in terms of fame. Maybe the Bronx is the best in the world...but those sort of debates are subjective and everyone has a different opinion. I would love to visit the Bronx, but I think that driving through New York City without stopping is much easier than battling the traffic and all the other headaches that come with that heavily populated area. Plus there are a lot of other tourist attractions to see in the city, and I believe that New York City is a completely separate, week-long holiday on its own. There is still a chance of us visting the Bronx Zoo, but I'd put it at 50-50.
@pygathrix: my wife isn't a big fan of shopping malls (whew!!) or museums, botanical gardens, etc. She was a zoo fan when I met her, but not obsessed like myself. However, after visiting a number of zoos and learning about lots of animals she would now choose spending time at a zoo on holiday over a museum, shopping mall or type of memorial. She takes hundreds and hundreds of photos, and one day I'll have to begin posting some shots here at ZooBeat.
Last year we spent 6 weeks travelling around Australia for our honeymoon, and we visited 14 animal collections across the country: Taronga Zoo, Sydney Aquarium, Sydney Wildlife World, Melbourne Zoo, Melbourne Aquarium, Healesville Sanctuary, Philip Island Wildlife Park, Kuranda Wildlife Park, Crocodylus Park and Zoo, Alice Springs Desert Park, Adelaide Zoo, Monarto Zoo, Cleland Wildlife Park and Warrawong Sanctuary.
This summer I fully expect us to visit the Toronto Zoo and Montreal Biodome in Canada, and then at the very least 10 more zoos in the U.S. The one aquarium that we will definitely see is the Shedd Aquarium in Chicago.
