Bikini And A Sweater?

I leave for the cruise on Sunday, and while I am excited to be going I am having a minor problem. I have no real ideas on what to pack! Barcelona would seemingly be warm, as well as everywhere else we are headed......but I know it won't be hot. I'm planning on spending some days just relaxing by the pool reading in the bikini. But I also want to bring a sweater or two in case I get cold. And my biggest problem with any type of travel I do is I always, ALWAYS over-pack. I take the largest suitcase possible, and even if it's just a long weekend away I pack minimally 4-5 pairs of shoes (this trips shoes count has already surpassed that) and since shoes generally weigh more than clothes I panic about weight limits.

I am planning on wearing some nice jeans, a shirt and a cardigan or shrug on the plane (along with my peacoat) and a pair of black flats, and packing a skirt and a couple of shirts in my carry on in case my luggage gets lost, which is mildly helpful to my suitcase packing. And I need to leave plenty of room in my suitcase for things I buy (heaviest item being wine). Garret is letting me use his toiletry case I bought him for Christmas, and that should keep most of those type things all nice and together.

I am looking forward to relaxing, just letting myself breathe and not overthink things. But packing has always been the hardest thing for me to do. I mean, a woman can never have too many options!
