Need to finish my map!

Stressing a little, I got told today I need to finish my map by Friday, but eeeeep thats only tomorrow and thursday as I'm going to see 'Swinging into Christmas' (the musical theatre students production) on Friday! Realistically I don't think I am going to get it down, as its so detailed - I sometimes wish i had a magnifying glass when I look at the reference!Think I am going to have to take it home and finish ... thats if it fits in my suitcase.
