The hotel is gigantic, that's a fact. And it's equipped for conferences, even if it is not easy to reach.
The real problem is how it is managed. Most staff member I got in contact to were young (and that's not a defect in itself), inexperienced, possibly stressed and consequently unpleasant. The reception is severely understaffed, both in numbers and in quality: a two-stars hotel is more efficient if manned by willing people.
I arrived at past 14.00 and my room was not available, no idea of when it would have been. That morning, in order to reach Lillehammer when I was expected to be there, I woke at 3.00, so I was understandably upset. At 15.00 - on my request - the young lady looked indolently at the PC and gave me a room. Five minutes after, I realized that she had given me a four-beds room (see photo). I was too tired to protest, and anyway I had to stay only two nights.
By the way, the bathroom had no current-tap in it, and in order to dry your hair you have to do it near the TV screen, using it as a mirror.
No desk, no minibar. I have never seen a room like that in a **** hotel, never.
The conference rooms are equipped, so no complaint about that...
Breakfast is good - it's evident that there is a rush of hundreds of people over there. Dinner was acceptable.
The top was reached at the moment of leaving the hotel. I had to take a train at 13.11, and the rail station is not exactly over the corner. I asked a (well-mannered) young guy at the reception the evening before departure to make sure a taxi would pick me up at 12.45. He said this was allright. In the morning I paid the extras of my room (which was prepaid by the organisation I'm a Board member of) and asked a young lady to check if the taxi had been ordered. It wasn't, but she took note. At 12.30 I asked if the taxi was coming, answer was yessir. At 12.45 no taxi was there, and if I would have lost the train, I would have been forced to stay in Oslo and take another flight the day after. I had to raise my voice and told the older female employee who was at the reception that I was not satisfied, and she told me that in Lillehammer things went this way.
I think I will not return to Lillehammer, but in this case I will surely choose another hotel.

The Lillehammer Hotel might be a big hotel but it has a relatively cozy and comfortable feel to it. Being a large hotel, it was also good to have good size rooms rather than like some big hotels that try to squeeze in as many people as possible with pokey little rooms. The rooms are also warm with the temperature at a comfortable level, instead of being too hot like some hotels in Scandinavia.

The service was also warm and friendly. The hotel's meals are hearty and flavoursome. I had a house red with dinner and, by coincidence, found it was an Australian wine grown about 20 kilometres from where we live.

Coming from Australia, we had a bonus when we woke next morning, pulled back the curtains and saw snow falling all around. It gave a magical appearance to everything in sight. I had taken a photo from our window the night before of the ski jump on the hill across from the hotel but the falling snow next morning was so thick we couldn't even see the ski jump.
