I took my two boys some years ago when they were 6 and 10 years old - a brilliant experience! We went with Canterbury Tales for 4 days and worth every penny. We had a log cabin in the woods, and everything was geared to searching for Santa in the form of husky sleigh rides, skidoo rides, reindeer sleigh rides, with the help of 4 "elvs" who stayed with our group the whole time and played and entertained the children. We had all manner of ice and snow sports laid on. I'm pretty sure all food and drink was inclusive, except alcohol in the evenings, so we didn't need to take money with us when we went out each day, except for the last day driving back to the airport when we stopped off for souvenir shopping.
Both my kids still believed in Santa at that time, but because many of their school friends didn't, we didn't tell the children that we were going to Lapland until the very moring that we were leaving. This was so that they didn't get the chance to tell their friends before they went so that their friends couldn't say that even the Santa in Lapland was still make believe, and then spoil it for them.
One of the best parts was that Canterbury Tales tell you to get your children to write to Santa and to take the letter (surreptitiously) with you, where you hand it over in secret when you arrive. You also take a wrapped present that is requested in their letter and secretly hand this over also. (I photocopied my kids' letters when they were in bed, put the photocopies in envelopes, and it was these that the children posted on the way to school. The originals were handed over in Lapland, so when they eventually got to find Santa, he was holding their letter to him which made them think that their letters had really reached the North Pole, and then he proceeded to give them a present that was requested in their letter. Their faces were just magic!! Hope you can understand all this. I have just relived so many wonderful
