Which hotel are you staying at? - we stayed at the Rantasipi Pohjanhovi next to the river.
The main shops etc were closed on Christmas Eve, Christmas Day and Boxing Day. However, all of the attractions were open and the restaurants and the bars were all open.
There were also some little wooden huts open for most of the visit in Lourdy Square selling traditional wooden christmas gifts
We went to a fabulous mexican(I think)restaurant called Amarillo the one night.
Our package was:
Arrive on Xmas Eve - Dinner at hotel in the evening.
Xmas morning - Winter wonderland
Xmas night - Dinner at Santa's house
Boxing Day - The North Pole and Santa's village.
27th - shopping in the morning and then flew back to the UK in the afternoon.
These were taking on christmas morning: The little dots on the horizon are reindeers
and the beautiful huskies
I hope you have a fabulous time
