Hi Karla,
Disney's Animal Kingdom Villas - Kidani Village is a lovely resort! One of my favorite things to do at this resort is to enjoy my morning cup of coffee on my balcony. If you have a savanna view, waking up with your cup of coffee as the animals wake up and begin to wander the savanna is truly magical.
You will not need a car seat for either of your children on Disney transportation. Your transportation to and from Disney's Animal Kingdom - Kidani Villas will be by
Disney bus. You may encounter other transportation types around Walt Disney World, such as the monorail or boat, but do not worry, you will not need car seats on any of these.
As to getting groceries for your trip, there are a few options.
Johari Treasures is a merchandise location at Disney's Animal Kingdom Villas - Kidani Village that does sell sundries and a limited selection of groceries. Another option if you are a Disney Vacation Club member is to arrange to have groceries delivered to your room through Disney Vacation Club. You can do this by visiting the
Disney Vacation Club website, and under "Plan Vacations," head to "Pre-Arrival Checklist." You will need to log in, and then scroll down to "Order Groceries." From there, choose your resort for a grocery ordering sheet. Another option if you are not a Disney Vacation Club member or if you prefer is to use Garden Grocer. This group is not Disney-related, but will deliver groceries to your Walt Disney World resort. You can find them at gardengrocer.com.
I hope that these thoughts are helpful for you, Karla! Please do let us know if you have any further questions.
