Hi i did this holiday in sept 2008, we had barbara as our tour manager,she was great.About the balloon trip,as our holiday was 16 days we had 8 days safari in 4 parks, the only one with the balloon trip was the masa mara,which most of us did,even leaving the lodge at 4.15am! but it was fantastic.There were 6 of us our mini bus so we all had a window seat.The roof comes up so you can stand up to take photos,remember to take binoculars,they came in very useful,be prepared for some very rough tracks.One lady on one game drive needed the loo and edward our driver found somewhere to stop,so dont worry about it.In mombasa we stayed at the travellers club which was all inclusive.Dont expect to be able to sit on the beach its full of hawkers but when the tides out you can walk towards the sea and they dont follow you.The mombasa trip was good and i also did the dolhpin dhow,saw dolphins in the distance and we were able to snorkel on the reef.Take lightweight clothes and a waterproof or umbrella,because when it rains its torrential,but it does not happen very often.Im sure everyone going will have a great time,we all did.
