I'd say you're perhaps a little late in asking it...but that's where we're at.
If it were me I'd do:
Week1 - Session 1: Warm up 20 mins of continuous light climbing. 20-30 move circuit at around onsight level or just below, equal time on the wall as off. 8 laps.
Session 2: Warm up 20 mins of continuous light climbing. 15 move hard boulder, 2-3 mins rest, repeat 4 times. rest 10, do same again.
Pretty much repeat this for 3 weeks, with maybe half a session a week of bouldering.
Then just chill and go on holiday.
Where in Spain are you going, do you have a particular route in mind? Is it cruxy, continuous, any rests? Have you climbed 7a+ before? Doing a limit redpoint over 4 days can be tricky as you'll have no chance of rest, so you'll have to manage fatigue/recovery well.
