The main thing to remember is that, like Americans, the British do not enjoy an obnoxious group of young adults acting like they own the place. I mean, how many times how you glared at a large gaggle of giggling girls who refuse to move out of their five across formation? Too many to count? I thought so. This can lead to the cashier, waitress, or ticket taker to be short with you; not because they happen to hate Americans, but because it is rude to walk into the store, restaurant, or castle and act like you own the place. Luckily, this is easily fixed: be respectful of those around you. Remember that you are a guest in this country, so you should strive to be a good one. Also, never underestimate the power of "please" and "thank you." Common sense, I know, but you'd be surprised at how few actually use them.
Something some Americans might not know, however, is that the British think we are very loud. It's not the sound of our "accent" that makes them cringe; it's how loudly we're using said accent. We might think we're talking at a very normal volume, but to someone from a different country it may seem like we're shouting in their face. This doesn't mean you have to whisper, but it may be a good thing to dial down your volume a notch or two, just in case.

So, the myth that the British hate Americans: busted. They love to share their wonderful country with you as long as you're polite and interested.
Also, one more helpful hint before I go. Instead of asking what state you are from, they often ask what region you are from. Chances are if you just say the name of your state they'll know exactly where you come from. Hopefully this will prevent you from looking like an idiot when you're silent for a few seconds wondering if you should say the mid-west, America, or Wisconsin. It's too late for me (one cashier at Asda probably thinks I'm a little slow), but there's still hope for you!
