Maybe go part way and start with one of those brazilian cut thongs if you are questioning it but definitely bring both. You will be surprised how many there are.
I can't say I've seen a one piece and I've seen as many thongs as I've seen anything else. Men and women...and thankfully no one (well maybe someone) has a picture of me in one...but I've never seen such a picture...though it did happen...not one of my more comfortable moments. Craig...nicely done! Jesse in a thong or less doesn't ever surprise me.
I own 10 of them. I start off my day in a regular suit and by afternoon it's a thong. Less tan lines that way. You will not be alone.
Wear the thong you will be sunning the " girls" so sun the "buns" as well. Show off the hard work from the gym, remember. You are your own worse critic, everyone else will be enjoying the view and the results of your workouts. It's your vacation, live it up, step out of your home comfort zone you will have no regrets!
OMG! I remember those, too funny! I think the one with the floppy hat reading a bible was hysterical!
Okay...I should really go to bed (9 a.m. soccer-mom duty tomorrow), but I am going to find that thread and re-post it...stay tuned...
