Is it possible to reserve for the days they aren’t open for like 6 people? Or are they only open on weekends?

No u can't

No I'm sorry, not for a group of that size..

First of all you must be a superstar because why are you only taking 6 people for the whole day do need a whole entire skating rink that's a little bit selfish.Second of all I do not work for them call their .I am a customer just like you I had fun and I tell people I had fun if you need information call them I do not work for them & if you only wanted 6 people to go with you for the whole day buy your own skating rink stay blessed tho
