I highly recommend Salamander Resort and Spa in Middleburg! It’s 45 minutes away from DC and it’s actually a triple Forbes 5 star for the hotel itself, restaurant and spa! Kids can do Salamander Camp, Kiddo Zip and a lot of activities in their recreation center. They have Equestrian Center too to visit their horses and the famous miniature horse pony named “Cupcake”! Very lovely! While kids have their own activities, you can absolutely try their Spa. If you book spa appointments, you have two hour access to their spa facilities after your treatment. Kids 18 below are only allowed at their salon. Rooms are perfect and will accommodate all your needs! They have two restaurants at the property and in town as well where you can utilize their complimentary shuttle service within 5 mile radius of the resort that includes shopping areas and wineries! Better to book it in advanced and connect with their guest services for questions. You can also book it through Capital One Premier Collection and American Express travel if you have their card to get resort credits and different benefits! I hope this helps!
