We are doing B2B2B cruises out of Sydney and we’re planning on doing sightseeing in Sydney in between cruises. I’m wondering realistically how much time would we have once we get off the ship and before we have to be back on board. Departure time on all cruises is 6:45 although I’m guessing all aboard will be around 5:00. We don’t have to change cabins so that won’t be an issue. I understand the cruises aren’t linked and we have to disembark and be processed again and since this is our first B2B not sure how long this process takes or even if we are able to go sightseeing at all. Thanks for any advice!
