feedback on SKALETRICS parties at home

[debbieanne]

I'm thinking of hiring a skaletrics (and operator) to run a party at home with 15 boys and girls age 9.

Any feedback?
Does it keep them engaged for an hour and half.

The two companies i could use are Pro Slot and Get Racing as they both operate in North West London - any feedback most welcome?
