Hi Nick
I'll try and answer as much of your questions as possible.
Your daughter of 8yrs, there is a Kids Zone on board at the bottom of the ship and it appears to be good, but my daughter is 14 years old, therefore did not use it, but I do know other kids seemed to enjoy it!
You cannot choose where to sit in the Chanterelle Restaurant, as when you arrive on the ship you are given a piece of paper which has written on your table number for the whole time you are on the ship, so you will probably be sharing with another family or couple! Ours was fine who we sat with! The dress code for the Captains night is formal but each day you will receive a cruise news advising you of the dress code. I do know that there are no shorts or skimpy tops allowed in the Chanterelle Restaurant.
You can take electrical items, but the ships is only 110 volts! We got caught out by this, so our hair straigteners did not heat up as hot but we managed and in the end we bought a hairdryer on the ship which had dual voltage! There are hairdryers in the cabins, but they aren't that good for styling hair! Phone chargeers/camcorders will be fine so long as you have the two pin plugs! My husband took our laptop and this still worked fine.
Cabins arn't noisy, well ours wasn't, we were on Deck 4 in a Superior Outside Cabin, no 408 which was spacious! I cannot comment on your room on Deck 7 if you will be obstructed by lifeboats, but if you look at the deck plan, this should give it away.
The food is of excellent quality and varied, even my husband who is vegetarian was well looked after, as he does not eat much vegetables either!! The Maitre D made sure he was looked after!
Drinks are really cheap, £2.20 for pint of larger, cocktails £2.25, much cheaper than our pubs in England!!
Hope this helps, but if you need any further advice just let me know.
Have a great cruise!
Debbie
