The Venetian and Palazzo have increased their resort fees to $25 per night. In a new twist, though, they are allowing guests to decline the resort fee and then pay for things a la carte if they end up wanting to take advantage of the amenities the resort fee would have covered.
Their resort fee includes fitness center access, Internet access, boarding pass printing, unlimited local and toll-free calls, a newspaper and drink coupons.  Since the only thing of real value there is the Internet access, I think they will find that a lot of informed patrons will be declining the resort fee and only paying for Internet access as they need it. Note that the resort fee will automatically be applied to your room unless you decline it during the check in process.
