I am debating getting the Snorkel Package, one adult one child. We have a 5 yr old who won't snorkel at all and an 8 yr old. Knowing one of us will be with the 5 yr old the whole time we figured only one parent will be able to use the equipment at a time, can we share this? Meaning can my wife go out then trade in her wetsuit for a bigger one for me?
