well i only go to the jurong one before since the kallang one
didn't exist earlier.. i shall go recee then see how..
i love to go malaysia ones when i go for hols. cheap cheap
i went ice skating for the kallang one for quite a few time.
Even took up a lesson there. 
The skate are still rather new. And they offer both figure and
hockey skate. hokey skate is $1 more for renting. It is rather
empty most of the time. Which is good. I am thinking of getting a
skates for sometime liao. But they tend to cost more then
rollerblade.
Rolelrblade and ice skate are rather different. Ice skate tend
to be easier to pick up and more move to learn. rollerblade on the
other hand take abit longer and harder to learn the advance move.
Just my 2 cents.
