Visitor numbers to most museums and other places of interest are likely to be restricted, so read through your information pack as soon as you receive it to decide which, if any, attractions you would like to visit, and book in advance to avoid disappointment (alternatively, the web page for your chosen holiday mentions any particularly worthwhile visits within the Itinerary section, so it is worth re-reading this if you wish to make plans before you receive your information pack). The upside of forward-planning is that you’ll be able to enjoy these places with far fewer visitors than normal.
