MSC is a cheap priced product and the difference in cost between the balcony and lower grades is not that high. However if it is out of your reach then my next recommendation would be the inside cabin. The large mirror above the bed really reflects the light well and made the room seem much larger than it is.

The outside cabins (below) disappointed me, the windows did not let much light in and the rooms therefore appeared smaller and darker than I would expect for an outside cabin.

The inside and outside cabins though are actually the same size and the window is good for the mornings to see where you are and what the weather is like before getting dressed. The cabins themselves do not have lots of room and are basically just a place for sleeping and getting ready, however I like the decor of MSC’s cabins, the covers are all bright and colourful and give a cheery to the rooms. Which is just what you want on holiday.
