A party bus is generally going to provide you with a lot of space once all has been said and is now out of the way, and the reason behind this is that they are designed to be quite effective in terms of roominess since this is their main function. You should set aside certain spaces to make them specialized rooms that people can use for various things, and one thing that a lot of women would want to see that men often tend to forget about would be a powder room.
Powder rooms are basically spaces where women can go to touch up their makeup and make sure that they look as beautiful as possible to a certain extent.
Women that go to party buses in DC will have worked quite hard on their makeup, and they would ideally want to have a space where they can touch this makeup up again so that they can fix some of the damage that can be caused by sweat and the smears that can occur due to accidental human contact which can be inevitable in such kinds of events and occasions.
The women that you invite to your party will be overjoyed that you managed to think of them in this way. The fact that they can keep themselves looking beautiful will not go unnoticed, and you might find yourself making a few lady friends here and there yourself which certainly won’t hurt. Just make sure that no men enter this powder room unless they want to do their own makeup. This will make the powder room less effective than might have been the case otherwise so be really careful.
