Howdy Lisa!
Disney's Animal Kingdom Villas - Jambo House is such a beautiful Resort!! We stayed at Animal Kingdom Villas this past May and enjoyed every magical moment!
I wish I could give you an iron clad guarantee, but there are just so many unknowns. I have tried numerous times to book the Kilimanjaro Club Concierge but have not been successful thus far because the club level is such a popular selection.
Because the summer is such a popular time of year to visit Walt Disney World, I would highly encourage you to book a villa at your Home Resort of Bay Lake Tower at the 11 month window to ensure you have a place to rest your head after a long day in the theme parks. Then, the morning of your 7 month booking window, try to modify your reservation and move to Animal Kingdom. Be sure to take advantage of the waitlist option, if needed, as you never know what might open up.
You might also consider a split-stay at both Bay Lake Tower and Animal Kingdom if a villa becomes available in both Resorts.
Regardless of which Resort and villa location is available, I know you will have a magical vacation. I do hope you are able to reserve a villa with access to the Kilimanjaro Club Concierge! What an extra special treat!!
Thanks so much for your question and please let me know if you need any further information. Have a magical day!!
