Celebrity Eclipse

Having a choice of Concierge and Aqua for very similar price elected to take Aqua.
This gives free access to the spa and the cabins are all couples only (no children)
However best of all was Aqua Dining which was 'fine dining' every night at no additional cost (we never felt the need to book any other restaurant)
You can eat any time from 6.30 - 9.30 with no set time. although the earlier you get there the better chance of a window seat. The one catch - athough you can go into the restaurant at anytime you have to select a time early or late on booking. Do not put 'Anytime dining' on your booking as for some reason this gets you sent back to the Main Dining Room!!!!!!
This dining experience is worth every penny - one of our party was feeling unwell and the Maitre De wanted to send food to the cabin - it is a very personal service and makes you feel very special.
The ship is excellent as with all Celebrity ships but read any review from someone who has tried Aqua Class and see the response

best of luck on Eclipse I know you will enjoy it
