Hi Lain
Sorry for the delay - I had to get in touch with our agents in Kenya to get an answer.
The two sides of the hotel are connected so it wouldn't be an issue that your room wasn't in the same part of the hotel.
You are correct that you would be eating in a different restaurant from the half board people in the group so if you no longer wish to do that, please call us on 0844 567 8844.
I'd be surprised if you were the only person to upgrade to all-inclusive so it's worth checking again when you call.
Kind regards,
Olly, your editor
