99.5% Of my trips are solo. either with R Scholar, other companies or cruises ( this is expensive due to the supplemental), I encounter no problems we all share the opportunity to meet each other. I am single, therefore I have no choice because I love to travel. This year  2019 I travel to Germany Prague Vienna    Dec 15 days cruise with Princess , a trip  with R S  to New Mexico Nov 16. Traveling with another  person can go either way  great or bad. I prefer alone instead of sharing a room with a person that snore and we never know until we get to the room. I used to travel with my partner   after his departure I continue traveling solo however  during the daytime I enjoy the interaction with other members of the group. Solo is not that bad.  Provi
