Like anything in life, from washing up liquid to cruises there is a range for everyone.
If your cruise is reasonably priced but you have not cruised before you will probably be delighted with it and the passengers on it. If you have only cruised with Silversea (expensive) and then cruised on an 'ordinary ' cruise, I would think you would have a different point of view!
Our cruises have been mid-upper level and we have sat with people who cruise full-time (incidentally, much younger than us), people who owned half of Texas and a peer who used cruises to reach his Caribbean island! We cruise every year-ish, don't own a part of Texas and don't have a Caribbean island! These people could have looked at us disparagingly but... they were not snobs and we all had a great cruise. We have also met and are still friends with people we sat at dinner with years ago.
I am trying to say that your cruise will be what you make it. You will probably be sitting with like-minded people and if you don't judge others, they won't judge you! It is said that the only person able to make you feel inferior is yourself !
Cruise.co.uk (or the American site which is even better) is a mine of information and you can join a forum, similar to this, by putting in the date and ship name. You will then be able to 'meet' with people who will be cruising with you before you sail.
On every ship we have sailed on there has been an informal restaurant where you can eat similar food to that in the main dining room without the need to dress up.
To those who hate cruises...... but have never tried one, please don't comment until you can justify your statement. Not everything is for everyone. I hate the idea of a coach trip with early-morning starts and being told when and where I can go, etc., but.... I would not presume to tell anyone else how awful they were until I had tried it!
We enjoy cruises, unpacking only once, whilst seeing cities in a range of countries, which would be impossble any other way. Yes, they are just taster days but give us an idea of if we'd like to return.
Oh, if you do book, ask for a table for 8 -10 people (if you would like to sit in the dining room). That way, you will have a variety of people to chat to.
Tipping is usually mandatory often being pre-paid so you know what you have to pay when you book. Some cruises have tipping included in the price.
Go on your cruise, Ethel. Perhaps buy another top or two, which may make you feel a bit less worried but don't forget that others will be in the same boat (tee hee!) as you.
If you enjoy company you can join quizes, dance lessons and much more, so cruises are very good value. That type of thing is not for us so we find a quiet corner on deck, put our feet up and read in the sun, watching the sea rush by. Magic.
It is a wonderful holiday and once paid, you need spend very little money on your trip. Tea, coffee, soft drinks (from machines but there is a range) and water are always available. There is food (on Celebrity Cruises, anyway) available all day long, so you can eat whenever you want to.
I hope you ban any worries - book and try it. I bet you won't be disappointed! Let us know if you do go......
