We're off to the Canary Islands for a week (DH, DS,DD and myself). Not been abroad for a couple of years.
I'm intending to spent 90% of my time lazing about but there will be the Siam Water Park to go to 
So apart from:
Sun Protection
Swimsuits
FlipFlops
Shower gel/shampoo/dental/face cream
Couple of cover up dresses
Couple of pairs shorts
One long dress
Loose trousers
Tops to go with (everything must go with at least 2-3 other things)
Plimsols
Nice sandles
Small handbag
Tote bag for carrying all the gear
Hair wrap
Scarf for evening if I get cold (unlikely. Flipping hormone furnace , me)
Oh, tablets etc.
Magazines (airport)
What have I missed?
Minimal make up and my glasses are transitional so no sunglasses needed.
