I think that one night we (me, wife, DD6 and DD3) would like to go one night to the Boardwalk area to check it out and watch Epcot fireworks. I assume taxi is most direct, but we will not have a car seat and I am concerned that taxi will not have a seat. What are are best options to get there, and back? How is the view of the fireworks at the Boardwalk area?
