My first cruise

This july I will be on my first ever cruise and I’m really looking forward to it, altought I will be with only my family,so I will not gonna have somebody of the same age group as me. Can you tell me where on the boat is the best place to meet nice peopple, or if someone in this group will be on that cruise 😅. I will be on the MSC Meraviglia, leaving Barcelona on 2 july, and stopping in Cannes, Genova, La Spezia, Rome and Mallorca.
