Omnipod at the Beach/waves/sand

Hi posted this on the omnipod group also. New to pumping with my 13 year old daughter.
Going to the beach in cape cod in 2 weeks. Have been doing well with swiming in the pool
Concerned about the ocean knocking off the pod. She wears it on her abdomen and backside as she is thin. I think she should wear a one piece bathing suit, any other tips?
also concerned about the sand getting in between where the pod attaches to the adhesive , should I be?
Should I put some kind of protective covering over it?
Will the sun bother it also or get too hot? Thanks for any info or tips you can give.
