Plane tickets – use your favourite flight search engine. If you don't have a favourite, try kiwi.com.
Tickets – if you're coming here in the summer season, it's best to get your tickets in advance. At least for The Beatles Story (here), and for the British Music Experience (here).
Calls and data – the UK is not part of the EU, so check with your provider for call and data prices. WiFi is common in hotels and restaurants and is free.
When to come here – pretty much any time except during the winter months. In the summer months of July and August it tends to be very crowded. So, it's best to come here in spring or autumn.
TIP – if you're a really passionate The Beatles fan and really want to see everything, then consider taking one of the "Beatles tours" in addition to your individual programme in Liverpool – the selection of tours on offer is more than wide. For example, Mop Top Tours have amazing reviews and they do half and full day tours.
