First time cruiser going on the Oasis of the Sea May 20 2018. I just had a really random thought come across my mind about the specialty restaurants. I made all the reservations under my name and for some restaurants I know you can purchase things a la carte (like at IZUMI). Hubby and I is traveling with his brother and his girlfriend, if they were to order anything for an additional fee would those items be charged under my bill since I made the reservation? I am just trying to budget, don't want to be surprised with anything. I hope my question makes sense. Thanks for any info!
