Unsure if you can be there that early. Not much to do or see. Guess your best bet is to ask your agent .
Likely yes. It's absolutely minimal there. Restroom, few vending machines. That's it. Besides being enclosed from elements. No other nearby places to go though.
It is not a fun place to hang out. The tour company should be able to answer your questions.
Not sure that you can? That would be a question that you should ask your travel guide or your cruise line agent!
