The big-name hotels empty out on the weekends and will give tourists a better deal. Chicago, Illinois: One of America's best-looking city centers, especially in the spring and summer. Spend a sunny day in Millennium Park, or consider an evening at Grant Achatz' s Alinea restaurant in Lincoln Park. Las Vegas, Nevada: It's never been so easy to score a deal on the Strip. Five-star hotels are marked down to three-star prices. Book a luxury suite(豪华套房) for $89 a night at www, trumplasvegashotel. com. San Francisco, California: It' s rare for a major city to have such an extraordinary physical setting—the views of the bay (海湾) from the hills and the Ferry Building Marketplace are striking. It's also a walkable city with great museums. You can visit the new California Academy of Sciences building in Golden Gate Park. Go early!

There are over 10,000 rosebushes, and because it's a test garden, the public has never seen many of these 550 varieties. The Rose Festival is one of the biggest celebrations in the city and runs May 22 to June 14.
