Hello! My family and I will be on board the HAL Oosterdam for July 26 - August 7, 2023. I tried searching the forums but couldn't find the answer to my question. A few of my party is interested in buying olive oil in both Rome (before we embark) and in Greece (during the cruise). Does anyone know if this is allowed to bring on board? I know the information about alcohol and I called HAL and the person I spoke with didn't know the answer. Any help would be appreciated. Thanks!
