We love each and every one of your children, however we want this to be your night off as well! The reception will be adults only. Let us know if you need assistance finding childcare. Recommended childcare is also available here: https://www.whitehousenannies.com/for-nannies/
Washington D.C. has mandated all hotels and restaurants require proof of Covid19 vaccination. Make sure you have a copy with you for check in and attendance!
Unless you plan on exploring further outside Washington DC, a rental car is not needed and most likely more expensive than a cab or Lyft/Uber from the airport to the hotel. The DC Metro is also an easy cheap option to get around. Everything else is within short walking distance!
