All the travel suggestions are great, but if you don't plan on traveling:
use these 30 days to make a change in your life. We all have things we'd like to change about our lifestyle, but always blame a busy work schedule, or whatever excuse we can find.
In those 30 days, you can decide to start exercising, eat healthy, etc. Chances are when your back to work, you just won't be able to stop what you already started since you've gotten used to it.
I did this with exercise and eating healthy. I had a chance not to work for 2 months, and I started swimming and doing weights daily. I've been back to work for 8 months and I can never not exercise regardless of how busy work is, I'll always find time to do some exercise and make sure I eat properly. It's a really big change in life
OR...
make a long list of movies and TV shows you always wanted to watch, get an 8 DVD Netflix subscription for that one month, and eat junk food. Sleep on your lazy boy, wake up, continue watching your DVDs.
Make sure the only time you get fresh air is when you go out to mail your DVDs back.
Also make sure you have some videogames to occupy you while you wait for the DVDs to be sent back to you.
You should do this for the 25 days in the month, then use the last 5 days to detoxify your body from all the junk food and soft drinks you have consumed, to clean up the mess you have made in your house, and to readjust your clock back to work time.
I also had the opportunity to do this as well
