I did get a bit queasy the first day but quickly got used to it. I saw sea sick things in the shops on board but you can get travel sickness bands and tablets from the chemist before you go.

Also ask if they have an unlimited soft drink option. It cost us about $7 per person per day but entitled you to unlimited fizzy drink, mock tails and milkshakes. There's also a coffee one if you want proper coffee. Otherwise there is unlimited water, instant coffee and tea available.
