Punkybugs

Hi everyone! Hubby and I will be taking our first cruise ever on Navigator of the Seas soon and I was wondering if anyone else has cruises after having gastric surgery. My husband had gastric sleeve a few years ago and cannot eat meals in large portions. It’s better for him to eat several small meals or snacks throughout the day. We can adjust for the reserved dinner times but I’m wondering about the buffet and the MDR for lunch and breakfast. Is it possible to visit either the Windjammer or MDR for small bites a couple of times every few hours? Will they allow us to take leftovers back to our cabin? I appreciate any advice from anyone that has had gastric surgery or a family member that they’ve cruised with that has. Sarah
