Am running out of time to exchange a week of timeshare we have already relinquished through Interval International. Am seriously considering trading for a week in a one-bedroom at the Sheraton Vistana in March. What matters to us mostly is that it is CLEAN and convenient to Disney (for instance, how close to Downtown Disney? How frequent and dependable are buses to and from Disney parks? Bus to Universal?) I seriously doubt that we will touch a pool (have one at home and prefer to use this vacation time for things we can't do at home, that is, visit Disney and possibly Universal. Are the one bedrooms spread throughout the resort or in a newer or older section? Any input would be much appreciated!
