A number of studies paint an optimistic outlook for the summer travel season, as more consumers plan to relieve their pent-up desires for travel. Travel agencies also are reporting a rise in bookings to Europe despite the persistently high airfares. ASTA's latest Summer Hot Spots survey found Italy leading the list of top global travel destinations. Within the U.S., Orlando, Fla.; Las Vegas and San Francisco were the most popular travel hot spots. "Some things never go out of style. A family-friendly destination such as Orlando, and a destination like Las Vegas, with thrills and excitement, are perennial favorites among Americans," ASTA President and CEO Zane Kerby said.
