Vacation deals in Nantucket

The folks at the Perrin Post have written about the Hot Dates, Cool Rates promotion for discounts on rooms in Nantucket for spring and summer.
For instance, at the luxurious Wauwinet, the summer rate for a standard room is $746 per night (including tax), but on some mid-May and June nights the rate falls to $247.
At the White Elephant, standard rooms fetch $675 per night in summer, but you can get a room for $192 per night for some late April and early May nights, in late April and parts of May and June the price will nudge up to $214; and some July and August dates will only set you back $439.
Rooms as the Cottages at the Boat Basin will usually set you back $538 per night in the summer, but for a number of April nights, you can score a studio cottage for $137 per night, and you can snag rooms at a savings of at least 29 percent on select dates in May-August.
The Jared Coffin House is normally $170 per night, but in April room can be had for as little as $109; on some May and June dates $115; $137 for select other days in June.
I just spoke to the folks at Nantucket Island Resorts, which is running the promotion and they say that, despite what you may see on the website, you can still snag one of these deals through the end of April -- and they are considering extending even farther. But if you're sure you want to go, why wait?
