We did the dinner-show combo with Hollywood and Vine in Oct. and loved it. Here's what I experienced about reservations...
When I made the reservation at the 90-day mark, which was the standard at the time, the only times that wdw had opened up for the package were 4 PM and 4:30 PM. So I made one for 4:30 and they told me at that point to call back from time to time, as they usually opened up later times closer to the date. I did that, and every time I called, the cm gave me different info...'yup, they'll be opening up times any day now', 'times will open up about 48 hours before', 'they never open up other times', 'it is sold out and will remain sold out so you might as well save your dime'. In the end though, about 2 weeks before, they opened up whole slough of later times, so we ended up with a 5:30 reservation, which was perfect. Time to eat leisurely, then stroll over to the show. And the food at H&V was :slurp: :slurp: :slurp:
