Las Vegas-book now through V hols or wait for VA release

Hi looking to book next April (easter school hols) ...having looked at Virgin holidays they are offering fly drives £1624 for PE each or 1 week at the Cosmopolitan (one bedroom fountain terrace) for £6250 in total
As this is peak season....would it be better to book now at that price or wait for seat releases at the 11 month mark. Not sure how the dollar rate will affect prices.
Hubby's 50th so he wants to be there for those dates and prefer direct flights
Any thoughts or advice?
