Thoughts on Malta.
We were there for a touch less than a week.
I can compare it to Cyprus and Lanzarote, which I think are fair "comparables".
It's a shorter flight than either. It feels more crowded than either, although last time I was in Cyprus was a long time ago now.
We are both capable of dealing with heat, but this was a bit much even for us.
Valletta is beautiful, and we will likely return to explore more. Mdina is also outstanding, a little like Carcassonne in some ways.
