Go Ape vouchers?

[WindFlower92]

Was thinking of getting this for my SIL's kids - age 7, 4 and 2. Asked her and she said this is something they would be interested in, however I'm stuck on which one to go with that would be suitable for the age range. I know the 2 year old probably won't be interested anyway, so if there's anyone who has done Go Ape or used the vouchers, which pack is most suitable for a 7 and 4 year old?

Our go ape has 2 courses, one for children and one for adults. So you’d want the children’s More basic one For a 4 and 7 year old, especially if they don’t done it before.
My 3 lovely, although we’ve moved on to the adult one now as they are all old enough now.

Some sites do have two levels for children. Our 9 and 7 year old did the harder kids one (think Adventure+) at Moors Park. It was much longer and considerably harder so challenged them a bit. There was also no member of staff at the zip wire to supervise / encourage them. If it is their first time I would definitely go for the easiest level. It sounds a great present.
