The holidays are usually fun from start to finish,so I suggest you take the plunge and book.I will have been on 8 JY holidays by the end of the year and had fun on all except 1 (I loved Sicily) but not a very nice crowd,very intellectual lot or so they thought they were.You won't regret it so book it.Poland is great,Switzerland is beautiful,Sorrento is pretty and scenic,Norway is memorable...ooh I could go on! Anyway Good Luck whatever you decide
