Four people in a room

[Sleepy425]

We did one balcony room with our two teens and it wasn’t too bad. We spend so little time in the room anyway. And when we were there, DW and I were on the balcony most of the time, so didn’t feel crowded at at all

When my sister and I were 15 and 16 we shared an inside stateroom on Royal with our parents. When I was 17 I shared an inside stateroom with my parents (sister was in college so she didn't come). We never had an issue. We always shared one room when we did any kind of vacation, so we knew nothing different. And this was back in the day when formal night meant FORMAL night - we would bring so many gowns and dresses, and shoes to match each. We had SO MUCH luggage.
Now we get balconies, and I have 4 kids. My parents usually take 2 and we take 2. Our next cruise for Thanksgiving is the first time we have 3 rooms, and that's only because the price difference was a whopping $200.
If it is in your budget to get 2 rooms, go for it. But if it means getting an extra vacation if you do one...I'm all for the extra vacations (or longer).
