Welcome back Ray and Helen!
I'm glad to hear your grandson loved his first cruise.
I had the MRSA scare just before I left on my May 3, Century cruise. It turned out be a "regular" staph infection but I was amazed at how fast it grew from a small bump to a small chicken egg in less than eight hours.
They treated it like MRSA and I was on the Sulpha and Cephlaxyn for two weeks. There is still a small BB like bump under my skin but the doc said that's normal.
Good to have the both of you home safe and sound.
