perhaps you are all missing the point. It is not up to you if it is not worth it,it is up to the individual parents .Is that pool that you had put in last year a good investment ,absolutely not but you get to decide how you will spend your money.For the 2020 girls the chance to go away with 60 or so girls their own age ,stay in hotels together, swim in the hotel pools together,have team pizza parties,make new friends ,learn lacrosse,may be worth every penny.My 2019 played last year and had a blast.As far as playing up in age they won many more games then they lost and the dangerous thing is silly.
