We used this service twice.
First was on Alaska Inside Passage cruise. Worked fine, as advertised, bag was in stateroom before we arrived.
Second was on British Isles Explorer cruise … not quite as good.
Pickup was fine. Used their ( that is, DHL’s) website to track the bag. It showed arrival in England, and shipping to warehouse in London, then showed that it had been delivered to the ship. It showed delivery to ship even tho the ship had not yet arrived at port! When we arrived at the ship, bag was not there and nobody knew where it was. Thru good effort by Viking staff who contacted Luggage Forward, as well as my own calls to Luggage Forward, the bag was found in London and sent to ship in time for departure.
So, did it work? Yes, but with a lot of unnecessary angst from misinformation.
Will I use them again?
Hmmm…the jury is still out on that one.
Maybe.
Probably.
