I know this spam guy is gone, but as for his question (in case others are looking) - I've been there where there are groups of guys (the 4 NYC cops a few years back come to mind) - and they were a blast. It's all in how you present yourself!
Be it at TTR or in the general public I treat women and couples the exact same way…which is with respect. This is my 3rd upcoming trip solo and I have never had a problem because my respect for others always guides my actions. Mackattack I'm sure your a good guy and will have a great time at TTR but your conduct and level of respect will dictate everything during your vacation irrespective of TTR being majority couples or singles. Good luck to you and enjoy your time at this amazing resort.
