You're a category II, but the cutoff for category I is 15% bodyfat, so let's use that.
280g protein plus 200 or so tag-along calories from green veggies, a tablespoon of olive oil and 10g fish oil daily. Do this for 12 days, then a two-day refeed. Eat two pieces of fruit and some protein, the about an hour later, do a tension workout before you begin the refeed. Google tension workout if you don't know what this is but basically, it's a full-body workout, 3x8-12, about a minute between work sets.
Then begin the refeed:
Day one refeed: 180g protein, 900g carb, 50g fat
Day two refeed: 180g protein, 250g carb, 50g fat
Load 20-25g creatine during both days of the refeed. I suggest dissolving it in hot water, as Will Brink suggests. Remain moderately active during the refeed - it'll help you reglycogenate. Then resume the PSMF until you go on vacation.
During the PSMF, walk an hour or more daily. Train twice a week, full body workout as per my homework 1 in my sig.
Supplement with 10g fish oil, a multi, a multi-B, a gram of vitamin C, 1g potassium, 1g calcium, 500mg magnesium
Happy starving!
