Hi I think a lot depends on which area of Lapland you go to.
There are a few different resorts available
Levi busy ski resort but gets great reviews
Saariselka (where I went) remote village 20 miles from Russian border
Rovaniemi city so has all the busy features of a main city
Yllas Quieter ski resort.
Glogirl. My four day trip with thomsons went like this....
Day one. Fly with thomsons. Check in desk full of staff with Santa hats etc. all airline staff also wearing Santa hats, breakfast included for free ...all Santa themed with chocolate elves etc. kids sing carols down the intercom on the plane, competitions etc. all the kids get a free Santa pack with Santa hat, colouring book etc for the flight out. I believe this is all exclusive to thomsons.
Arrive at 2pm and get kitted out in thermal gear (all provided). Rest of the day free to go on the mile long tobaggon run! It's fab. There's sledges dotted around resort for anyone to use, saariselka only has four hotels so very quiet.
Day 2 - pick up at 9am travel 10 mins to santas resort (Google). Given vouchers for free excursion and left to explore on your own. Here you can try driving mini skidoos, go on husky, reindeer and snow mobile rides ....all free. Then have lunch in Santas house, meet the blacksmith elf, take part in a Lappish ceremony. Then go by snowmobile sled to search for santas cabin in the woods where it is a log cabin with a private meeting. Present included.
Free time for the rest of the day from 2:30pm.
Day 3: free day with free gala meal included - this is a big Xmas dinner, Xmas crackers etc with dancing etc followed by a firework display.
Fly home day four.
On day 3 you can pay for optional excursions, we did a 2.5 hour husky ride which is without doubt one of the best things I've ever done in my life! Me and dh each drove huskys with a child each in a sled stopping at a remote cabin in the woods for reindeer pita sandwiches and hot berry juice over the fire. It was breathtaking. Just like narnia!
It was an Amazing holiday.we paid £2200 four four days inc everything but the added excursion (that was about £300). Even though B&B, Lapland trips inc lunch on activity day and gala meal so not strictly only B&B.
Whole thing is Worth every penny!
