I stayed on Coral deck with 2adults, one child and the cabins were very spacious! As for the drinks it's fairly expensive for soft drinks at £1.45 for a coke or £1.95 for a non-alcoholic cocktail but alcoholic drinks and similar to the UK prices around £2.50 - £.
Drinks are about same price as you would pay in pub here its about 1.40 for can of soft drinks for kids we used to bring cans of juice on at each port i dont know any thing about bronze cabin always done diamond or coral check your island cruise book if you got one from travel agent you will enjoy your cruise we have done island for 5years hope ive been of some help.
We've stayed twice in cabins on bronze deck - once in inside ones and the second time outside ones.Both types were great - lots of space for 2 adults and a child - nice bathrooms and plenty of storage areas. Soft drinks were £1.40 per can , alcoholic ones as stated in previous answer. Hope you all have a great time - we certainly did.
Forgot to add to my previous answer that the bronze deck cabins also seemed to be a lot quieter than those on higher decks - no kids charging up and down the corridors.
We stayed in an outside cabin on bronze deck august 07 first time on the escape although we have cruised on the star previously, we are a family of 6 with 3 teenage children taking up 2 cabins, the cabins didn't seem at all cramped with 3 of us in each, there's plenty of storage space and everything was spotless, apart from a little engine noise which you quickly got used to there was no noise, to be honest our kids didn't spend to much time in the cabin and were usually to be found in the lookout with their Friends or on deck, there seemed to be plenty going on most of the time to keep them all occupied (although 2 kids in the swimming pool would fill it up) there were a few other children on board and all seemed very well behaved, drinks are pretty much the same price as you would find in pubs & resturants at home, we are cruising again on the escape this year 8th april, we luv it!...see you ther.
