I will be in Marco Island in May for three nights, and one in Naples. We are all foodies, and want great food, in a fun, lively atmosphere...something funky on the water, something upscale, a hole in the wall with character--we like it all. As for food types, we love seafood, Italian (although boht Italain restaurants we ate at in Marco were not every good), Japanese/sushi, Asian, just no French or boring Continental menus, please! We are also in need of lunch spots, too!
As for Naples, something that is more upscale with great people watching, great outdoor dining, or off the beaten path..all are great.
