We rode out of hotel signature this March. It is a good setup and the free shuttle downtown is a bonus. My wife loved the ice hotel (its north of town and you have to drive your own vehicle to it). The hotel is very snowmobilier friendly. Only thing I'd say is go mid week. The traffic in the area on the weekends is detrimental to a good holiday. We left on a saturday morning headed for Saguenay. There was lots of fresh grooming, but by 10 am everything along the north shore of the river (TQ 3 essentially) was trashed. We met hundreds and hundreds of sleds. We didn't find smooth trails until we swung north on TQ 83. The scenery is great, was loads of snow and I do believe the grooming is very consistent, but the traffic was unreal. I can honestly say I won't go back on a weekend to the Quebec City / Charlevoix area. I'd start from St Raymond and try and stay further north. That or drive right through to Saguenay or Tadoussac.
