GETTING THERE: Sesame Place is just north of Philadelphia, 165 miles and approximately three hours from downtown Washington. Take I-95 north to Exit 46A/Route 1 north and follow the well-marked signs to the park.
STAYING THERE: The Courtyard by Marriott Langhorne (5 N. Cabot Blvd., Langhorne, 888-236-2427, www.marriott.com) is only a quarter-mile from the park, with room rates starting at $169 on weekends. The Sheraton Bucks County Hotel (400 Oxford Valley Rd., Langhorne, 800-325-3535, www.sheraton.com) is even closer: Walk one block to the park. Rates start at $192. For lower-priced lodging, try the Ramada Inn Levittown (6201 Bristol Pike, Levittown, 800-2RAMADA, www.ramada.com). A six-mile drive from the park, it offers weekend room rates starting at $101 in August and has a playground and game room for kids.
BEING THERE: Sesame Place does not sell single-day tickets. An Elmo's Passport is good for two days and costs $38.95 plus tax for children and adults (kids under 2 are free). The second day can be used any time during the same season. Parking in the general lots is $10; locker rentals cost $7, plus a $5 refundable deposit. Park hours vary by time of year; for most of August, the park opens at 10 a.m. and closes at 8 p.m. The full season runs from early May until Labor Day and then is open Saturdays and Sundays for the rest of September and much of October. Swimsuits are recommended, and swim shoes or flip-flops are the best footwear.
EATING THERE: Inside the park, there are several different restaurants or cafes that offer pizza, chicken Caesar salads and hand-carved club sandwiches, among other options; the kids' meal (a hot dog or chicken fingers with french fries, served in a souvenir Elmo lunch box) costs $7.95 and doesn't include a drink. For dinner, there's a slew of family-friendly chain restaurants close to the park, including -- if you dare -- Chuck E. Cheese (1283 E. Lincoln Hwy., Levittown).
