I'll be going to a Honolulu for a conference in January with my nondiving wife and baby. I gather from reading here that Oahu is not the better of the islands for diving but I doubt we'll have a chance to visit other islands. I'd still like to get in at least one or two dive trips (more is always better..). I am OW with 30-50 dives (it's been about a year since I last dove, so have to dig up the log). Any suggestions? Any suggestions on activities that are doable with an infant (we did Costa Rica with a 5 month old and managed to do quite a bit still, including hikes and boat rides) ?
