I am planning a coast to coast trip starting from london flying to boston then to new york, washington DC, Orlando, Dallas, Pheonix, Las Vegas, Los Angeles, San Fransciso, Seattle, then back home. I know im missing alot but lack of funds make this trip some what budgetted. I plan on using greyhouond coaches to get about although uncomatable i dont mind coach travel and will see alot more than if i was on a plane. I will be traverling on my own and though im only going to be 21 i think this will be ok. I'm just wanting some peoples opinions on what i should try and see, will the coach really be that BAD! and safty tips.
