I just spoke to VV as I’m sailing on the 7th of August for the Irresistible Med cruise. They said they would have sent me an email on time for me to book the test, but have kindly given me a code to book it myself. You’ll get a parcel with tests, which you can then take whenever convenient for you. You need to download an app but you are supposed to get the results asap without having to book an appointment. Given we will travel to Barcelona a few days in advance this is quite helpful.
On another note, happy to meet some people on the same cruise as me, feel free to reply to this post 🙂
