Wanna take my kids for a spectacular year end holiday. Price is not an issue. Looking for novel ideas.

How about a trip to Scandinavia? It will be winter and it is absolutely gorgeous and a icy wonderland. If your kids love the movie, "Frozen", winter in Sweden (where I am currently based) comes pretty damn close. You can catch Aurora Borealis (northern lights), play with snow and experience an authentic white Christmas. If you head up to the North of Sweden (Kiruna, Lulea, Pitea), you can even go ice fishing, ride on dog sleds and try reindeer meat. The Christmas market in the city of Jokkmokk is one of my favourite winter memories. Be warned though, it can get really really cold -- but if you're properly bundled up, a holiday in wintry Sweden can be super spectacular!
