Sorry to be negative but there is so much to say it would be far better if you could be more specific. ie which ship, which cruise, how many, cabin type, your food/drink preferences and which ports. There is enough knowledge out there to build a big picture for you. Now to be positive, RCI is good to cruise with. If you like to get involved they are great and if you want peace4 and quiet there are areas to get away on your own. Good sailing, Neil Dow.
Neil is right. To help you it would be better if you'd provided more information. However I do support his comments regarding RCI. They are one of the better cruise lines and we loved our Venice/Athens/Mykonos/Rhodes/Dubrovnik trip last year. Our only complaint is that the cabins are on the small side compared with Thomson and Ocean Village.
We went on a Baltic cruise with RCI Navigator of the Sea in June 07 and could not fault a thing one of the best weve been on, and this was about our 18th infact we liked it so much we are off again Sept 07 on Legend of Sea around the Med. Dont worry you'll enjoy yourself the staff make sure of that.Spoil yourself try breakfast in bed, we liked it so much we had it there every morning.
