I've read some conflicting information regarding these tests for cruises departing from Europe.  We are sailing out of Barcelona this June but are arriving a few days before the cruise so we aren't able to test prior to leaving the US.  Can we pack these and take with us and do it on our phone from Barcelona or are we better making an appt at the airport in Barcelona?
Also, do these satisfy the testing requirements for return back into the United States?  
 

Thank you.  The information on found on the RC website was under the heading for cruises departing US ports, Puerto Rico, and Canada.  Made me question it since it did not list European ports.

My first visit was on Harmony in June 2019.  There were 6 of us, my wife and kids plus my parents.  We splurged for a Oasis Pool Cabana and it was $499.  We used our onboard credit to cover some of it.  It was a great hangout spot, but not sure I’d pay again.
I did purchase two water park tickets for me and my son, they were $74.99 each. We went down the big slide after almost a 2 hour wait. We got there about 30-45 min after docking.  After that we went to the Cabana and never came back.  It was my fault for not going back later and doing some of the other slides, but my son got busy with other activities.

We got off the ship as soon as we could.  I did go to the Cabana first to get that squared away, but once that was finished my son and I headed over.
Again, we should have gone back and done more things.  He got busy with the pool, lunch, and then the beach.  We had a great time don’t get me wrong, but I certainly didn’t get my money’s worth on the water park.
