Can't answer your question re: ouside cabin (as we had an inside one), but we went on a Baltric trip on the Celebration in July this year. We love Thomson cruising anyway, but this was our favourite ship (we're in our early 40's). The ship is a bit old and dated, but more than makes up for it in the friendliness of the crew - they are all lovely, the entertainment is good and the audience participating quize shows are usually pretty funny. There is also 'quieter' places ie: there is a top bar, Horizons which usually has a jazz group playing, or the Explorers Lounge where there is a classical duo playing. Food is good standard in the Restaurants and Buffet and the ship is kept very clean.
I wish I was coming with you!!
Thomson cruises represent excellent value for money. The Celebration is a nice ship- not luxurious in its decor etc, but its public bars and lounges could compete with the likes of Princess. Entertainment excellent, catering for every kind of taste, service first class, food very good quality, variety etc. Its not necessarily totally informal since it does have gala dinners and people do dress up for dinner but if you dont want to you can always eat in the buffet restaurant which is also very nice. Outside cabins have a porthole or a picture window,they are kept immaculately clean, turned down in evening with towel sculptures, chocs on pillows etc. Enjoy your cruise should you go ahead with it!
We love this ship. We have travelled in both standard and deluxe cabins. For a good view you do need the deluxe cabins but you do pay well over the odds (unless you get a special deal) Bearing in mind how very little time is spent in the cabins the question is how important is the view. We personally would opt for one of the standard higher decks cabins. We are also in the same age bracket. If you go we are sure you will thoroughly enjoy yourselves weather permitting.
