You can still do what you want on a singles cruise, your party's with the group and activities are included, but you choose what you want to do. I've never heard of anyone being invited to the parties without paying to be in the group so I wouldn't count on that happening. I did see a man who wanted to join, end up paying extra on ship to be part of the group, so he could go to the parties and eat with the large group of singles. Most escorted singles groups have between 100-250 people roughly. Halloween, and New Years get 200-400 singles. Usually more women then men. I have done non singles cruises also but met very few other singles all were women most I'd say ages 45 and up. Other then that most people on the ship were coupled up or family's. I had fun on both, made many friends some of whom I travel with, don't go expecting romance, go to make friends and no expectations, if it happens it's a bonus, message me any questions. I have gone with 3 different singles company's. Hope this helps.
