Hello Silla
Welcome to Just You and of course the community.
Just you do a number of trips, However I Can recommend the Black Sea Rivera, Which is an all inclusive beach holiday. In agreat little location and resort. And the sun can be expected. It is also a reasonably priced holiday. Although this is a sun, sea & sand holiday, There is opportunity to visit further a field, Where you can sea the archetecture of churches and buildings. Another trip I can definately recommend is The Austrian Lakes. Although this is not a beach holiday. There is opportunity to catch The sun by the very large lake which is in the hotel garden area. One of the excursions on this trip is a visit into Salzburg, And you will be amazed at the Archetetural structures of buildings and chuches. Both trips are only about a 2 hour flight from Gatwick.
All the best
Andy
