Phil:

If you are fair and concerned about the sun, all I can say is that you should do everything and anything to protect yourself on the PG.
It is a wonderful ship & you will have a great time.
BUT
Shade on the open decks is a rare thing

Silly hats, towels, whatever..... do respect the sun.

I remember telling my bride on day one to watch certain people on day 3 because they will be lobster red by then. Imagine pouring on tanning oil & baking in that sun!

Phil: be smart & you will be ok.
