Hi all. Looking to travel to America for my 50th birthday in August with my gorgeous wife. We want 4 or 5 days in New York then stops in Philadelphia, Washington D.C., Pittsburgh, Niagara Falls then 4 or 5 days in Toronto. Or start in Toronto and do this route in reverse. Looking for advice, inspiration, alternative stops or places to visit from anyone who has been to this region. We have a budget of £5000 and a travel window of 2-3 weeks. Been looking for weeks and seem to be going round in circles! Any help or advice really appreciated. Thanks in advance.
