We've moved the sleeping hotel for iDate2011 Miami from the Shore Club to the National Hotel.
The National Hotel is @ $209 per night, lower than the Shore Club ($250) the National is a really nice hotel. Its close to the Convention Center and across the street from Mansion, where the awards ceremony will be held.
We kept an eye for lower room rates at equivalent hotels nearby. The Shore Club was not willing to reduce the rate. We didn't want our delegates on budgets to find other facilities to sleep at. Although we had parties there and the place is fairly cool, their reputation on sites like Yelp and others isn't exactly stellar. From our dealings with them we weren't sure how they would treat our delegates.
If you currently have a reservation at the Shore Club, you can cancel as long as it is within 7 days of the conference. So my suggestion is to cancel (they probably charged your credit card already...you will get the $$ back on your credit card), and then reserve a room at the National Hotel.
