For once I agree with 7C's comment. Reviews are just that. Additional comments on the review can be written on the Forum, if one wants to go that route, but should identify the situation and make a comment. If the person who has a comment on a trip reviewer's review, and as 7C has stated, IF the person has also taken the same trip, then they can request GCT to add to their original review, or if s/he hasn't written their review yet, the person can write their review and include comments on your view of the situation /destination, town, restaurant, etc. I've seen some reviews just as I'm saying. Can't tell you which trip, because I don't look at all the trips unless I've gone on the trip, or am thinking of going on the trip.
