* Spending..........using credit/debit card for everything vs "changing" cash - check on your credit card - many add a fee for currency conversions.
* Cell phone usage.....cost ? need? text?......Chargers ?? - Get details on your plan before you go. You can get no-contract temporary plans over there if necessary.
* Tablet........my wife never goes anywhere without her Samsung pad....lol - If it's cellular, turn that off. Use Wi-Fi.
* car rental vs daily bus pass. We aren't on a tour ...have rail tickets betwen cities already, others say the pass works well. I actually really enjoyed driving there, and only almost killed us once
* Dining ?.........Pub food okay ?............we'll be in there anyway. YES!
* Weather (supposed to be in the 40 - 50's ) we weren't really going to pack much - Yeah it'll probably be pretty dreary especially around the coasts.
HAVE A BLAST! I was never a Guinness fan til I went over there, now it's my go-to beverage.
