Me too! Where are you going to?
Have bought lots of immodium (for grownups) and dioralyte for everyone. Have also stocked up on hand gels (3 for 2 in M&S). We're also taking probiotics (tablets for adults and powders for kids) from today until we've been back for a week.
In terms of sun protection, I've bought a few UV suits, UV swim hats, big floppy hats and sunglasses for the DSs. I will be stocking up on lots of high factor suntan lotion in the next few days.
I'm hoping if we get the boys into the holiday clubs at the hottest times of day, step up (bottled) water intake and be generally careful with hygiene and sun exposure, that we'll have a good time!
We've had Hep A jabs, but I've decided against any other types of jab since we are also AI, and don't really expect to do any extreme trips or eat outside the complex. Apparently if you get a tummy bug whilst you're over there, it's worth visiting a local pharmacist who could sell you antibiotics that are specific to the local bugs.
I've read that there is a chance of rabies over there, so avoid petting local animals, and also some wierd bug which can be found in lake/pond water, so don't go paddling apart from in the sea.
HTH!
