SAN ANTONIO, TEXAS

Whether you and your little one are ready to fiesta or siesta, San Antonio is just the ticket. For starters, Sea World San Antonio can serve as a cheaper alternative to tourist-mobbed San Diego and Orlando -- single-day tickets cost up to 30% less than at its sister parks. Junior might also enjoy seeing the dinosaur bones or the exploring the giant tree house at the Witte Museum.

For a leisure itinerary, swing by the Alamo or unwind in Brackenridge Park which boasts wide open spaces, gardens, waterfalls and a miniature train ride. You can also take your tot for a boat ride on the San Antonio River or stroll along the River Walk, where you'll be serenaded by Mariachi bands among the festively lit restaurants and shops. Bring a stroller or baby backpack, though, because there's no guardrail to keep your curious wanderer out of the shallow water.
