I am making my trip come together. This is how it's most likely going to look.
Land in Boston:
Spend 2-3 days in Boston, maybe 3 if I can go from there to Niagara falls & then back, otherwise 1 night in Niagara falls as well.
Then Greyhound to New York. Spend 3-4 days in New York.
Then Greyhound to Washington DC. Spend 3-4 days Washington DC 3 days
Then Greyhound to New Orleans thou I will probably need to stop on the way and sleep somewhere, unless I can stay on the bus the whole time. Spend 5-6 days in New Orleans.
Then either the Greyhound to Houston and spend 1 day there or fly (via Huston) straight to Los Angeles. Spend 3-4 days in Los Angeles.
Then Greyhound to Vegas. Spend 2-3 days in Las Vegas
Then Greyhound to San Francisco. Spend 3-4 days in San Francisco
Then Greyhound to Seattle. Spend 5-6 days in Seattle
Then fly from Seattle to LA & then over to South America (because for some reason that's cheaper then flying straight from Seattle).
Now I will work out how many days I will actually get everywhere and how much rooms (or dorms) will cost. And also how long I need everywhere since that depends on what I want to see. So next I will post list of thing I want to do etc.
