From a guy's perspective, I take a carryon legal 21 inch rollerboard, but I check that bag, and take a smaller tote with me in the cabin when flying. I wouldn't get on an international flight without a carryon bag with at least a couple of days worth of clothing and my toiletry essentials, lest my checked bag gets lost. However, I don't want anything larger than a carryon legal bag for storing on trains, storing in the trunk of a car, carrying up stairs, or getting on very small elevators. The tote plus carryon gives me the capacity of the larger bag, with with more flexibility.
I could get by with just a carryon bag if I had to, but I will also be the person carrying maps, papers, guidebooks, and some other stuff that the rest in my party won't have to carry as result, but we'll all be carrying the same bags--one checked carryon legal bag, and one tote.
You will need spending money to cover drinks, lunch, souvenirs and different small incidental costs whilst on tour such as cheap excursions costing under $20 like a visit to the Maasai in the Serengeti
Be aware as well that meals are not covered whilst the truck is parked up in Jinja due to the many different activities on offer, some of which are inclusive of meals.
Tipping is customary in Africa, so budget for gratuities if you wish for guides or drivers who provide good service such as your guides whilst gorilla trekking. Again it is at your discretion, but your tour leader and driver will appreciate a tip to acknowledge their hard work during your tour.
For some excursions extra transport is needed to get to the start point such as to the gorillas, and lastly some campsites en route also have simple huts or chalets on site. If you feel like a break from camping and youd like an upgrade at some point it is well worth having a little bit of money budgeted accordingly.
The recommended spending money for the East African Encounter is: US$440 - US$550
In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West.  Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans under this regime, the new East German state legally restricted virtually all travel to the West in 1956.  Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately does not always turn out in favour of Democratic [East] Berlin."
