No there won't be but there are usually plenty of facilities where you could go and fill up a small thermal flask and head back to your stateroom. There is also room service but that is not always very speedy. As far as bedding is concerned you should put this as a special request at the time you are making your booking. If you are dealing via a travel agent they should be able to find out from the cruise line if the request is being made if booking via the internet then a phone call to the cruise line would be necessary then ask for a ref you can quote when you make the booking.
Yes there are tea/coffee making facilities in the room, although the tea bags were awful. I recommend you get some teabags from the garden cafe(twinnings english breakfast tea,herbal teas etc) if you want a decent cuppa. You can also get fresh milk there at all times. The beds are the most comfortable i have come across and i slept really well which is not like me. Ours came with a mattress topper even though we hadn't requested it, i'm not sure if its standard in all cabins. Hope this helps.
We have just come back from our Jade cruise, reply to your question. Yes tea making facilities our in all staterooms, the matteress topper is called bed bliss and it is excactly that, best nights sleep I've had in years. wish I could have brought it home with me. Have a good cruise and enjoy life is what you make it.
