Hey Dickie - depending on which days off at work are the problem, you could fly to Malaga and hire a car. 3hrs or so to Almeria according to the AA so not exactly close but later flights available.
If you don't need too much sleep and could leave early on the Friday, you could get the Easyjet flight from Stansted at 18.00 (gets in 21.55, so not to bed 'til 1ish) returning home on Sunday at 21.55 (arrival 23.50).
Or if you really can't leave work until later, Luton - Malaga at 19.25, arrival 23.10 and back Sunday 23.55, arriving 01.40 (or back to Stansted if you can get the train on the way out and Mrs DD will pick you up).
Go on, if you can, it'll be fun
