This is always a hard question to answer. Tolerance varys so much from one person to the next so what one might find O.K. and comfortable with, the next person will be very uncomfortable with. Atlantic Shores is a place for anyone as long as you have an open mind. It caters to all but does get a larger percentage of gay clientel than most hotels/motels down here. The only area where it might be "in your face" or you might even get hit on is at the pool area. The pool area is a lot of fun and very much a social gathering place here. It is open to the public so all walks of life are there and it is a clothing optional area so you will see all kinds of things pierced! LOL!
I don't think you will look out of place but please understand you wouldn't be the first guy (straight or otherwise, or the last guy to stay there by himself but sometimes some of them have other agendas (if ya kow what I mean ;) )
I hope this didn't confuse you to much. Have a great trip!
