When you are organizing your luggage, you should keep in mind that airlines have baggage limits and generally you will be restricted to one or two checked bags. Bring a small carry-on bag that fits the budget airline restrictions (Ryan Air and Easy Jet) for weekend trips.
If you are hoping to use any of your electrical devices in the UK, you will need to come prepared with plug adapters and perhaps a voltage adapter as well. Plugs in the UK have three prongs, and a simple adapter fits over the end of the North American plug so it can be used in the UK. These adapters are relatively inexpensive and can be purchased in luggage shops or electronics stores. Bader Reception also stocks these items.
Voltage converters (for use with equipment without a built-in converter of its own) are more expensive and may be required for personal computers and other items. Before you leave, you should check any electrical devices you plan to bring to see if a converter will be required. Most laptops have a built-in voltage convertor but please do check.
Please Note: Plugs in Continental Europe are different than in the UK. Some adapters can accommodate both types of plugs; if yours doesn’t, you should consider purchasing a separate adapter for travel to the Continent. The UK uses 220 volts, however in Canada and the US the standard wall outlet voltage is 110.
