Hello....Husband, 10 year old daughter and I going on 8th cruise 12-26 to 1-4 ! I'm going to get our own snorkel gear this time. Daughter wears prescription goggles, so just needs the snorkel and flippers. The snorkels with head straps all seem to be the type that go up the center of your face and I don't think she'll like that. Are there any that have a head strap that don't go up the center? or are the ones without the strap easy to keep in mouth? I don't mind buying one that comes with a mask, we just don't need the mask and I kind of wanted a strap on the snorkel. I've not been snorkeling in years. I will be buying hubby and I some gear as well, whole set. Thanks!
