Hi, i'm a 23 year old from the UK plan on visiting my girlfriend who's
spent the summer working in ocean city, maryland.

I've travelled quite alot through Europe and Asia but have never been
anywhere in America, and so I have a few questions

Where would be best to fly to to get to Ocean City? New York or Baltimore?

That depends on the cost of tickets, but Baltimore is a lot closer to
Ocean City, MD than New York.

I'd need to get a coach or bus to ocean city; but the greyhound site won't
let me reserve tickets since i'm not from the US, are these services always
full or can i just 'turn up'?

I don't know about buses. Try calling them to find out.

Will a regular VISA credit card from the UK work in US ATMS (probably a
silly question but just to be on the safe side!).

I believe so, but it cannot hurt to contact the bank who issued your
credit card to confirm.
