Just read your introduction post Wandra. When my husband and I travelled we always wanted to go alone. We did not even like going with another couple. We always loved to cruise and as you said enjoyed meeting other people but we were definitely loners. We also really enjoy each others company and are very compatible.
Then we started this cruise business and we found we needed to go along with some groups. This turned out to be fun and all of a sudden we started to really enjoy the social aspect. Now I just cant imagine it any other way. We went on the Silversea trip with just one other couple and thought "wont this be great" wrong!! We missed being with a group. Those who know us now know how much we have changed. Interesting how lifes adventures can change us.
You just sounded so like me about four years ago I could really relate to your post.
