Disney’s Vero Beach resort offers the Disney brand name and quality at a beachside resort along the Florida Atlantic coast.
There are lots of vacation club villas (studios, and 1 or 2 bedroom set ups) as well as standalone cottages (including 3 bedroom beach cottages) that can accommodate most family sizes.

There are various recreational activities for you to frolic on the land or in the sea.
So, if you’re looking to combine a Walt Disney World land holiday, with a “seaside” stay at Vero Beach, let me know. Vero Beach is about 1.5 hours from Orlando, so the combo holiday is certainly do-able.
