It used to be a symbol to show your hospitality and morphed from there. Today, the pink flamingo meaning is used as an indicator of a swinging lifestyle. This type of symbol is not as common as the others, but it does exist.
Options for Romance are EndlessWhen it comes to romance, few vacations deliver like a cruise. While some traveling couples enjoy stargazing from the ship's deck with a glass of fine wine, others find their bliss at Cloud 9 Spa with a couple's massage featuring seaweed or hot stones.
There are single cruisers on almost every ship. Some sail solo and others are in friend or family groups. Dining arrangements, onboard activities and port tours make meeting like-minded people easy. Also, it's socially acceptable to strike up conversations with others throughout the ship.
Getting laid on a cruise is not as easy as it may seem. First, you need to make sure that you are in the right place at the right time. Cruise ships usually have designated areas for singles and couples, so be sure to check out those spots first.
The upside-down pineapple is the unofficial symbol swingers use as a secret way to identify themselves to other swingers on a cruise ship. If you see an upside-down pineapple on clothing, a cruise ship door, or accessories, there is a good chance it's a swinger.
In very general terms, cruising attracts adults ranging in age from their 30s through to their 80s, and you will not find a ship full, exclusively, of 20 year olds.
