That's why I never use the Valsalva (sp?) "hold your nose and blow" equalization method. Even if that works going down, there is no equivalent method for depressurization upon ascent. It's possible to overcome a blockage going down that will not clear coming up.I would definitely get the ears fully checked out by an ENT specialist. I had a dive buddy several years ago that had a lot of trouble clearing, took a long time to descend, then blew out his ear drum with a reverse squeeze on the ascent.
"by the dock" is ambiguous. Do you mean by the ferry pier downtown?
By a specific dive shop dock?
By a cruise ship pier?
Knowing where you are staying may impact your dive shop choice.
First and most important is to get a competent doctor's assessment that she is OK to dive. I would assume that this also verifies that she is capable of equalizing her ears.
.........All of this assumes that she WANTS to dive as opposed to doing it for pressure-related reasons.
