The new undertaking by the Disney Vacation Club will be Disney's largest time share to date. The vacation rental site is 20 miles south of Downtown Orlando.

Disney officials declined comment on the estimated hard construction cost of the new project. But area construction industry estimators familiar with comparable time share jobs tell GlobeSt.com the ballpark number will be about $15 million or $250,000 per unit. That number compares with luxury hotel developments that have been built or are planning to be built in the Orlando area, industry estimators say.

"Disney always goes first class, so this construction estimate may be on the low side," a private construction company not associated with the project tells GlobeSt.com on condition of anonymity.
