Well, since my wife retired in June and we moved to Lancaster, Pa., we've been eyeing bus trips. So far, we've done one -- to Cape May, NJ, at a cost of $89 each. That included the bus trip and a two-hour boat tour of the area. Day trips seem to run somewhere between $40 and $149, depending on where the trip goes and what admissions are included. For example, a trip to Baltimore is $42 if you just do the bus, but if you go to the aquarium, it jumps to $67. You can take a day trip to New York City for $50, but if you want to take in a Broadway show, it may cost as much as $235!
Railfan content: a trip to Altoona, which includes a visit to Horseshoe Curve and a ride on the Amtrak "Pennsylvanian" over the Curve between Altoona and Johnstown for $120. Based on that, I'd say a $55 trip that includes a train ride is probably in the ball park.
