Expedia is offering you your last night free when you stay at over 1,300 hotels. It is pretty simple to take advantage of this one. Simply stay 3, 4 or 5 nights at one of their qualifying hotels, book by May 31st (that is pretty soon guys and gals) and travel through June 15th.
So this is the weekend to get away. Call in sick on Monday...just get out there and travel a bit. After all, the work will still be there when you get back.
