I have been on the Jewel and it was fantastic!! you will have to pay about £25 for a good meal in their special al-carte restaurantsbut for a one off it is worth it HAPPY CRUISIN.
I gave you the costs of the speciality restaurants on another thread you started. $10pp equates to £10 for two people. Where on earth could you get a first class meal for that sort of price?
About $10-25 per head but well worth it at least once on your trip. Outside cabins on deck 4 have a porthole that allows you to know what the day looks like but not a lot more but if I'm going for the cheapest trip I'll go for these cabins rather than inside as they are less disconcerting when you wake and dont know if it's morning or night.
