I LOVE our DTD store in Chicago, and hope the Long Island one is just as good or better (most of my family lives on LI and I grew up in North Babylon).
Our DTD store in an upscale regional suburban mall (it is not in downtown Chicago) has twice-yearly events with giveaways, food, characters, etc. We were one of the grand prize winners of a 5 day all expense paid trip to WDW worth $10K won at a DTD event drawing in the summer of 08 (and we had never won ANYTHING before) so we never miss an event if we can help it! The events are mostly to sell more points to existing members and entice new members to buy (our DTD does separate events for existing and prospective DVC members) but they are still fun, low pressure, and serve as wonderful Disney and DVC "fixes." And it's fun to go in the model, even if you've been twenty times. There's always good branded stuff given out, from passport covers to luggage tags to leather-look portfolios, DVC logo binoculars (plastic, but cute) and other stuff like that. Plus pictures with characters. It's a great deal...hope they repeat it at Roosevelt Field.
