Having said all that we have always enjoyed camping holidays ,small yacht holidays ,gulet holidays so to us cruising with Majella/Tui holidays seems quite luxurious but to others it may not !
We have enjoyed 3 cruises with Tui now called Marella and have enjoyed them all . All in Europe .The boats are not new and swimming pool areas can get busy but you can always find a quiet space elsewhere. There are a variety of eating areas casual but we usually choose the restaurant for evening where we can dress up! We go with friends and we have only ever done one excursion ( leaning tower of Pisa last year) but usually have a good look around whenever we are in port and have seen some lovely places at our own pace. I think probably these cruises are good value for the money you pay rooms fine the staff are very friendly and the food good.
My husband and I set off on a Marella cruise to the Far East in a couple of weeks. We have cruised a few times before, always 5 or 6*, but friends recommended 4* Marella to us. It seems great value for money. Any one an experience of this cruise line, hopefully positive!
