We are just waiting to disembark from Fantasia after a short cruise out of Santos. We have lived in Brazil for 4 years now so it's our third cruise here.
Very, very noisy and virtually impossible to get a seat at all around the pool deck and, as said above, extremely loud music is played all day around the pool. Music in the bars will mostly be sertaneja, forro or mpb. The couple of european musicians seem to have gone.
The buffet is the same, very long queues and difficult to get a table. I'd recommend breakfast and lunches in the dining rooms where available.
With regards to the buffet, only paper cups for coffees were available and disposable plastic cups were used for beer in all the bars onboard.
Table service, if available, is very slow in the bars, instead you need to queue at the bar for one bar steward to input your order, you are then given a receipt to have to queue again to give to the bar tender.
I don't know of this is all peculiar to MSC cruises in Brazil, it was the same on Preziosa in April, but we are doing a TA from Rio to Barcelona in March and if it's the same we will reconsider whether to continue cruising with MSC.
It's a shame because we just reached Diamond.
