How many ride can a 2yo child can enjoy here? And a 7yo child?? Thank you.

A bunch

It goes by height. If your 2 year old is 40" then they can ride a few rides, the website has a height requirement chart for each ride. If they can't ride, you can still ride with your 7 year old (assuming they are above 42") if you have another adult with you to do a parent switch. Your 7 year old can go with each parent each time.

If your child not enough height, not many. Yeah if you're child height over 120cm, have almost 10 attraction

I'm not quite sure how many rides your 2 year old can ride but I know that your seven-year-old can ride a lot of them if they are as tall as they require you to be. No problem

There are not a lot of rides for little kids and the lines are so looooooooong. My kids are 15 and 14 and got frustrated.
