I am organising a family trip this Christmas. We have done the East Coast of USA and were planning Europe but after a brief (week) trip to Philly & NY a couple of weeks ago my children are now keen to go and do the West Coast probably starting in NY going up to Boston and then down to Florida ending in a cruise around the Bahamas. We would be away 3 weeks approx with two travelling and one on the cruise. Is there plenty to see coming down the coast and what do you suggest. Where would be best places to spend a little time already looking at Philly, Washington, where else would be a great experience for 16 and 13 year old? Should we motorhome or being winter (having been in that cold March week) would we be better off driving and stopping in Motels. Drive the east coast and loved it? Kids would like a touch of snowboarding as well where would you recommend a couple of days?
