My husband and I have 2 weeks off at the end of August and want to book 1 week away during that time. Only conditions are
IT MUST BE SUNNY 
and
IT MUST BE BY THE SEA, other than that we're easily pleased.
Now here's the killer question

Do I book now (bearing in mind there's only 4 - 5 weeks to go) or do I keep my nerve and book
VERY last minute to try for a bargain?
