Family suitability is high: Children will enjoy the Mystic Aquarium in Connecticut, the Please Touch Museum in Philadelphia, and the boardwalk amusement parks in Rehoboth Beach.

Fatigue management: Plan stops every 2 hours. Recommended rest zones include the Southington Rest Area in Connecticut (milepost 31) and the Chesapeake House in Maryland (milepost 45). Both have fuel, food, and picnic areas. Avoiding driving between midnight and 6 AM is advisable due to reduced visibility and wildlife activity.

Hidden off-route spots: Just off I-95 in Rhode Island is the Beavertail State Park in Jamestown, offering dramatic lighthouse views and tide pools. In New Jersey, the Cape May County Park & Zoo in Cape May Court House is a free, world-class zoo. These require a 15-30 minute detour but reward with unique experiences.

The primary route is Interstate 95 south, with a detour onto the Garden State Parkway in New Jersey to avoid New York City traffic.
