Hi Leica!
We absolutely love the Animal Kingdom Lodge. The rooms there are very spacious, and beautiful! Kidani Village has its own pool and recreation area, and DVC member lounge.
It also boasts its own sit-down restaurant - Sanaa, with African-inspired cuisine with a touch of Indian flavors. I highly recommend it!
In January, the weather is difficult to predict this far in advance. I have been swimming in WDW in January and February, but I have also been there in those months when it was freezing cold and we needed parkas to keep warm! So, please check the weather channels before you go to see what Mother Nature has in store for you the week of your visit!
The pool itself in Kidani Village is called "Samawati Springs", and features a zero-entry pool and a wet activity playground called Uwanja Camp. I hope you get to enjoy them while you are visiting!
Since you love Fantasmic! at the Hollywood Studios, I would suggest that you consider booking an Advanced Dining Reservation for the
Fantasmic! Dining Package, which combines dining at one of 3 restaurants in the park with designated seating for the show. You will have a great meal and be guaranteed one of the best seats in the house for your favorite show!
Have a wonderful trip to Walt Disney World!
