How old are your kids? I’d be more willing to let my children if they were teens wait with the other adult in their cabin than if they were younger. What is their boarding time? If you can’t get a consistent straight answer from Carnival, consider keeping FFTF and just board when your kids do. I hope it all works out for you.
Last time at Mr Sanchos, a few years back, we were able to pay as you go. We paid for food and drinks separately. At the time they also had all-inclusive but it wasn’t mandatory. Is it still this way? We don’t want all you can eat/drink. Thanks for any info!
