I was lucky to be offered a free trial of the Baggex service before our cruise on QM2 from Southampton in June.
I was very impressed. Communication was very good, collection was on time, we were sent a photograph of our bags arriving at the terminal and they were in the cabin when we boarded.
When we disembarked we handed them over in the terminal and they were delivered as agreed a couple of days later.
If you have a complicated journey or are travelling alone I would definitely use them again.
If you have any questions, just ask here or post on the special thread where they will answer
