NOTES
General
I contacted Mountainside Lodge, where we stayed last year, regarding a three-room suite:
"The room you are requesting is not available for the dates that you are looking for. We do have a studio loft available for those dates that would cost 375$ per night plus taxes and 14$ per night for parking. In this room there is a queen bed upstairs with a washroom and private sauna. The downstairs has a queen pullout bed , twin trundle beds a kitchen , fireplace and full washroom. If you would like to book or have any other questions call us Thanks Mountainside Lodge"
