My brother and I have to be gluten free. We raised this with Exodus weeks before the trip. Not sure if our experience is typical - but post trip we've suggested to Exodus that they tell people that certain dietary requirements cannot be catered for and that people should bring their own food to supplement what can be supplied and then get charged less for the trip.
The meal plan on our trip was VERY low in protein. When the group stops at the supermarkets in Kenya, we'd suggest that you stock up on nuts (or whatever you can find). They kept us going! We didn't know that nuts wouldn't be available in Uganda and Rwanda - so DO STOCK UP IN KENYA. Extra 'supermarket style' provisions were very hard to come by in Rwanda and not that plentiful in Uganda either.
We'd suggest drinking the bottled water from shops.
You will need to take toilet paper - and more than one roll. Don't waste your money buying the special light travel toilet paper from adventure shops at home! It won't do the job once your stomach 'goes African'. Make room in your bags for the heavy duty stuff!
Padlock has to be 38mm or 40mm. Nothing else will do. People on our trip found combinations hard to read once it got dark, so suggest a key lock.
Do take a good quality head lamp with a strong wide beam of light. This is a camping trip. Don't expect electricity.
Upgrades to rooms were available at Kembo Farm, Eldoret and Lake Bunyoni. Note: In Lake Bunyoni the permanent tents have amazing lake views but you can end up quite a way from the toilet (refer previous comment abouts stomachs "going African".)
We travelled September 22 to October 7 - it rained nearly every day (usually in the afternoon), so do take rain gear.
Jandals/thongs/flip flops/travel sandals were fine in some places; just not anywere there was mud. We found them a welcome cool relief from boots...and great for the VERY LONG DRIVING DAYS in the bus.
Do take your medications to the Masai Mara.
Charging facilities for various devices were ok on the bus -we'd suggest labelling your charger/adapter with your name as it can get confusing when people are using similar brands.
If you're doing the balloon ride in the MM (HIGHLY RECOMMEND!) or the white water rafting in Jinja, there are extra charges if you want to buy their photos and you'll need US dollars.
Genocide Museum in Kigali has a pretty good cafe with free wifi, gifts and ok toilets. Food service is a bit slow though, so eat or drink first.
Ideal - is taking an adapter for your tablet/ipad/laptop (or using a microsim) so you can transfer your photos onto it at the end of each day. It was awesome viewing them on the larger devices and you'll save battery power on cameras.
You won't find shops to stock up on electrical/camera gear whilst you're on the trip.
We only had wifi access three times during the trip. Suggest writing emails in draft form on the bus then sending as soon as you get to a connection. Lake Bunyoni the signal dropped out every time the power dropped out (which was often)
Electricity, flushing working toilets, toilet paper and lights will be occasional luxuries on this trip. It's best not to expect them... they don't call it third world for nothing.
Beds when you got them, were very firm. I say firm - my husband says rock hard.
If the trip notes haven't been updated yet - Bujugali Falls in Jinga don't exist anymore. The dam is there now. Some of us needed a quiet day that day, so we were able to buy a 'day pass' very cheaply for the pool at the 5 star hotel next door - highly recommend if you need some time out.
Also - breakfast after the balloon ride at the MM is AMAZING - but it's not a full english breakfast. Have asked Exodus to update the trip notes.
