Southern Gatwick Portsmouth recent customer reviews

Only problem we had was inability to go through gate initially. We were early, didn’t realize that ticket wouldn’t scan and open gate until about 20 min before departure. After trying repeatedly to enter, we finally asked attendant who told us to wait 10 minutes and retry. Suggest noting on ticket that departure platforms can be crowded with trains every few minutes, so tickets don’t allow admission until 20 minutes (?) before departure.
