Just arrived in Nice this afternoon to work for a few days prior to our Voyager cruise on Sat - I probably asked these questions before but pls humor me and help me out again

1. What time can we arrive and board the ship?
2. We leave from Nice and is there info we need to know about where to go once we arrive at port or is it rather evident? (Like....once you see the boat you're there... :) :) :)
3. Is there anything else I need to know about embarkation?
4. Why are cruise docs so heavy? (just kidding)

Thanks and I look forward to sharing my journey with everyone on this board.
