I know it's been a while since you posted, but I was curious which resort you went to that did weekly karaoke.
Yes, mostly at nudist resorts, at Hedonism in Jamaica was probably the most fun as prizes for winners and forfeits for losers. I enjoyed being up on stage but would never inflict my singing alone on anyone else, have always done it with others on stage with me. After a few drinks who cares though if it's not in tune it's just a singalong for everyone.
Wife and i have sung naked karaoke at resorts - it was great fun for the both of us being on stage naked for all to see
Yes, some wear thongs or lingere, it is sexy to see the women in shear lingere with nothing on underneath it
i've been to Shangri La a few times, loved it, very friendly people there. Last time we were there, they also had a huge hot tub like for 20 people. Plus there were walking trails too
Yes there are nice trails, if you go through the cacti though be careful, I got a spine stuck in my leg once.
Did you go on the river trail where they have all that weird stuff next to the trail like frog sculptures, and at one point they had a hand chair.
