A fun thing to do on a Saturday or Sunday when there is not a lot going on is to make your own personal spa. Going to a professional spa can be very expensive, but with a little creativity and a little preparation you can mimic the environment. First, I would plan out exactly what you would like to do during the day. Many people like hot baths, many people like foot baths, some people like to put cucumber on their eyes to reduce puffiness; whatever your preference, write it down. Next, look at each activity you wish to do and determine what you need to accomplish that activity.
Now that you have a basic plan for your afternoon, run to the local store and get some cheap bubble bath, some relaxing music, maybe some candles, or whatever you feel will enhance your “spa” environment. Tell your friends and family that you are going to a spa and you are not to be disturbed for two or three hours. This is a fun thing to do for yourself, but maybe an even better idea would be to do it for a loved one who had a hard week. Either way, it is a fun activity.
