It depends on what you’re looking for. If you like to plan your own itinerary and be flexible in what you’re doing, they might not work for you. I travel by myself and am not interested in planning everything out. So, for me, the trips are great. I’ve gone on 4 trips and canceled 2 last year (covid). The guides are great, the other people are a lot of fun, and I don’t need to worry about anything once I hook up with the group. I met a really good friend through one of the trips when we were placed as roommates, and we’ve gone on 2 more trips together, with another coming up.
