Showcase: Puerto Vallarta, Mexico

"It was a real eye-opener," said Brian Glynn, vice president of operations for the Meetings Management Group in Indianapolis. "This is a destination that seems to have something for everyone." Added Sheryl Allison, meeting coordinator for the American Board of Pediatrics in Chapel Hill, N.C., "I came to Puerto Vallarta not knowing anyone and feeling a bit apprehensive, but I left with a lot of new friends. I'll be back."
