We had an hour doing this at Christmas. Good fun, and absolutely nowt like the real thing I'm sure.

As an introduction, that's a fairly low impact way of starting, so well done!! I believe there is still (or was) the Curling rink at 'Fentons', near to Tunbridge Wells and also one in Cambridge (sadly facilities are limited in England, with *probably* the top location being in Preston (The Flower Bowl at Garston)).
The difference between what I presume was a synthetic surface and on ice though is that, just like granite, ice is unpredictable and will usually 'change' during a game due to atmospheric pressures and also, sometimes simply the actions of your game on the ice surface.
Sometimes there will be very little 'swing' (curl) on the ice, so stones will play as straight as a die at the start of a game, but by the end, there might be several feet of swing (or vice versa) so the 'Skip' and the other players need to be very aware of how the stones are reacting to the ice surface.
The prices might seem major at first, until you realise that the cost of energy is high and for such a facility, the costs are huge.
At our rink, we pay something like £9 and hour, so if you add that up over a team of 4 (or 8) for 2 hours, then... 🙈
I pay a fixed amount by direct debit each month to my club, with me being charged for when I play (so if you don't play for a while, then your money starts to add up!).
