I too like to check in my bags when I get to the airport so DH and I always pay for hold luggage then I just take my 'holiday' handbag with me. It's big enough to get a book & magazine, sun cream, purse & phone but not too big to be a burden. I pack less & less as the years go by and I've just booked a week in Greece and leave a week today. As I'm holding a big family party this weekend and will have to get all work related issues sorted before then I won't have much time to worry about packing.
3 or 4 changes of underwear as I wash panties through while away. I tend to put on my swimming costume when I get up with a sundress or cut offs and a t shirt over it, then regardless of what we do I'm always ready for the sea or a pool (which is why I take 2 or 3 ExaltedWombat). Then cut offs and loose tops for evening, nights can get very hot in Greece, with a small bag for going out for dinner. Flip flops for the beach/pool & shoes/sandals for evening or trips. I too decant shampoo etc into small bottles and buy small toothpaste, shaving foam (for DH obv)
I stopped taking mosquito stuff to Europe years ago but then 2 years ago in Greece got eaten alive so I think I'll make sure I have some this time.
In my mid 60s, overweight, veins on my legs - hardly a beach body, but I don't care and can't wait for a week relaxing in the sun, eating, drinking and a few good books - bliss
