Sorry now lads. May be a stupid question but i never get anywhere if I dont ask them

I'm going too lanzorete next month and i was wondering if i asked someone on the flight deck on the way there would they let me have a look around the cockpit for a few mins or maybe have a sit in too see what its like during flight. I know it may be a massive security issue or could be a very ignorent thing too do but sure I thought I'd ask anyway
Thanks a mill
sorry if this is the wrong section
