You can't help but
fall in love with pretty Puerto Vallarta... one of the only historic colonial cities right
on the water... with
cobblestone streets and bougainvillea tumbling over adobe walls... but with a modern, sophisticated vibe.
Travelers can dine aboard a private tram that navigates the
cobblestone streets of Rome, for example, or hop
on board one of Amtrak's vintage train cars for the
fall's best New England foliage.
