Things for Non skiers in Borovets + sledgeing

Myself, Wife 2 kids and Mum and dad are heading to Borovets in mid January.
My mum & dad are in there early 60's so wont be skiing and my wife & daughter are going to try but i think they wont like it???
As a Family we love sledgeing ,is there anywhere you can buy/hire sledges and some where we could use them.
I've seen winter walks, snow mobiles and sleigh rides listed but not much info.

Any info welcome

thanks nyck
