Sun Lotion!? - sun lotion

I Goping holiday on Wednesday, I am very pale and sensitive skin
realllllllly sucks, because you want a TAN!
Every time I leave in a little tan but invites you to burn!
What factor sunscreen should I use to burn a little tan, but not yet too?
Other suggestions?
BTW, I will for a week!

Thanks in advance!
