This was my first RC cruise and Explorer was also the biggest ship I've been on. As a solo traveller I thought I might feel a bit overwhelmed by a big ship with just under 3000 fellow passengers but it was fine. It certainly didn't feel as if there were the 2800+ actually on board, and the public areas were certainly not too wide as to be overwhelming.
I'd been staying in New York for few days before the cruise and got to Bayonne by train from Manhattan without any problem. Waited for quite a while until a small shuttle bus turned up by the E.34th St station at Bayonne. Check-in was smooth and didn't take too long, considering the number of passengers they were processing.
I was delighted with my cabin - another first, being first time I've had a balcony. Wouldn't normally have considered it because when the ship's in a port I wouldn't get to use it. But my travel agent covered the upgrade and with 3 sea days at the start and end of the itinerary, I figured I would enjoy it and I did. Room Service breakfast on the balcony was great, too. The cabin was fine - especially as it was only for me - so space wasn't a problem. The bed and pillows were very comfortable, which is always a relief. My lovely cabin steward Lucy was great and had high standards, so the room was always left very clean.
Cabin 8952. Great quiet location. Well soundproofed - I didn't hear anything from cabins on either side and thought they were unoccupied until I saw luggage outside them the last night! I was a single, but there would have been plenty of space for two.
