I'm (M 48) heading to Jamaica solo for a week. Just looking for some general advice on possible interactions.

I'll be meeting a lot of people, most will be couples or friend groups in for weddings, etc. Not many solo travelers at the resort or nearby bars. When asked what brought me here solo I'm wondering if I should be honest and say I just love the freedom of traveling alone or say something like my girlfriend had last minute assignment and couldn't make it (social proof? Idk)

Anyone else travel solo and have tips?
