There are, but they seem to be skeezy "swingers" resorts...smeh.
I am surprised that so many famblies could afford to travel to Hawaii, with sprogs. I thought "times were tough" and "it's so hard and expensive", guess not so much. I am not all that surprised that Hawaii has lots of fambily bargains, like ours, their culture is very child-centric. However, I'm definetly surprised at the unmitigated gall of strangers who think they know your mind better than you simply because they've gladly joined the sheeple. If you've been giving all the kids the stink eye all day AND cap it with "We aren't having children", it's not too hard to think "yeah, these people might not be having children".
However, I must thank you very much for the heads up on when NOT to travel to Hawaii. I love that place and want to continue to do so.
