Headed there in March for 5 nights, and am moderately concerned about the temperature (looks like close to 30c during the day) given there's no AC in the room. I made the booking spontaneously when I saw a decent points rate, and then did my research after. Oops.
Also, looking at a flight that arrives in NBO at 10:25am - that should be plenty of time for a same day transfer to Wilson and flight to the reserve?
