As it says in the notes - there are some LONG drives and some of the roads are dirt and/ or pretty badly potholed. Ipod, camping pillow and, for your turn at the back girls, maybe a sports bra (seriously) would all be useful. I found all of the Senegalese hotels clean and perfectly fine for a grand night's sleep, again, as it says in the notes, the Gambian nights are a bit more basic but nothing an Exodus traveller won't have seen before. They do like their pillows hard however so, again, you might be glad of a softer camping pillow and many of us had our sleeping bag liners with us, just in case. The night in the desert WAS a bit cold so suggest a fleece, some long jammies and a bunnet if you really feel it.
I lost LOADS of stuff. Don't grudge it to whoever picked up what I was careless with as their need is greater than mine but I would make one warning....many of the hotel rooms have beds and other surfaces covered in brightly patterned materials and ~30watt light bulbs....might be a good idea to tell yourself to pass a hand over them rather than just a glance as you leave the the room. Also, if you're a night reader, might want your head torch or a wee reading light. Hot water wasn't as frequent as we had hoped so if you NEED "clean" hair everyday, might want to pack some of the dry spray shampoo. OTOH, the water is really soft so you'll get a decent lather in the lukewarm.
I took some wee bouncy balls and some cheap yoyos to give out to the kids. The bouncy balls don't bounce in the sand, doh, and the yoyos were TOO cheap. You've heard it before but they really wanted pens. Next time I think I will pack pens, balloons maybe and possibly some of that bubble blowing liquid. Won't last long but might raise a smile or two when you've got 20 kids under 5 all clamouring around you for some entertainment.
This was a super trip for getting a grand feel of the place. No two days were the same, yes the walking day, followed by the longest day on the bus, were a bit draining but the next day was the beautiful cruise along the empty river Gambia and all was forgiven.
