My family and I have rented a cabana on the family beach on multiple occasions and, for us, the tranquility and escape from the crowds is absolutely worth the rental fee. My husband and I would certainly rent, just the two of us, if we had the opportunity.
Honestly, I don’t believe I would choose a cabana on a solo trip for the simple fact that I would feel too secluded after spending a lot of time on my own. My husband, on the other hand, would do it in a heartbeat.
