mah,
I've done 4 other holidays (other than the Christmas one) with JY and Croatia with travelsphere. Two of my JY trips have been to America and would give "Americas Golden West" the nod over "Parks & Canyons", both great trips though.
As for my Europe hols not much between the holidays but if I had to put them in order (including Croatia) this is how I would rank them :-
1. Treasures of Andalucia
2. Discover Croatia
3. Discover Mallorca
But to be honest not done a bad holiday yet all been good and met some lovely people, one of the reasons I've two more booked this year "Austrian Lakes" in August and "Route 66" in October.
Also considering a Christmas hol again, been looking at Costa Brava, Lake Bled, Northern Cyprus to name three.
