Hi Lorna
Here are your answers.
Weather: It will be warm or hot, so your mother in law should pack accordingly,with plenty of light clothing, sunhats, suncream etc.
Rooms: All rooms are en suite.
Jabs: I would urge you to contact your GP about these.
Adaptors: The most common type used is the two flat pin variety but you may also see the three slanted pin kind. Buying a universal adaptor is a good idea, as you are covered for all kinds of sockets wherever you go in the world.
I hope she has a great trip.
Kind regards,
Olly, your editor
