I've only done ice skating and dancing for fun, so won't comment there (as I've only paid for admission to the rink, and for lessons for dancing - and you can find out those costs already!!)

But from my experience with other similar activities (gymnastics, netball, springboard/platform diving, softball, athletics, etc) the main cost was generally buying the different uniforms, and then actually getting to and from all the different practices and meets/matches, and associated costs (paying for busses, meals, makeup (for gymnastics) etc - which all get more intense if you get serious about it.

Ang "getting serious" can start young! By the time I was about 6, if I wanted to continue with gymnastics with the squad I was with, it was going to be 3+ trainings a week, plus meets ... and most of the girls by the time they were 12 were training 5+ days a week. And there were injuries ... I never broke anything, but plenty of the girls did ...

With netball, I was in 3 different teams (one with girls from my primary school which stuck together after graduation, an inter-school one with my highschool, and a local one through my church) meaning that I had trainings most nights plus three matches every weekend (two on Saturday and one on Sunday).

And diving (which I started when I had to drop out of two of my netball teams) was three practices and (two wet, one dry) every week, with competitions every couple of weeks.

Almost all my friends who did competitive swimming were at the pool every morning before school, meaning their parents dropped them off at the train station around 5am, for them to get to the pool in town and do 30 mins warm ups and 60 minutes training with time for a shower and change before catching the train to school ...

Point being that you might want to find out now how serious the ice skating and dancing might get in upcoming years ...

And if you have an ambitious or competitive little girl on your hands, you might want to find a club that has a more social focus, rather than one which has an expectation that they will be competing seriously in the near future ...

Particularly if you think she will want to do other co-curricular activities (choir, band, art, etc) as well.

Activities are awesome - and both ice skating and dancing are wonderful fun, and she can make great friends, get wonderful exercise, and of course learn new skills and have a great time!

But I'd be picking the team and the activity really carefully - which is what you seem to be doing
