Thanks, all. It's reassuring to hear that they can be accommodating.
I was worried that if I only eat "lunch," my options might be more limited than dinner times. The menus I've seen list a lot more options for dinner, so I'm hoping they can do something more dinner-style at lunch times on sea days.
I don't need the same staff, I'd just heard that's how they handle it at dinner when you pre-order (I assumed so they can track the order). But if it's just associated with me regardless of server, that's totally fine with me.
It's my first cruise so I'm trying to work out those little details, expecting to be a bit lost on the first day or so. I know I'm supposed to try to talk to them early to work out the special diets stuff but having never been, it's hard to picture exactly how to do that. All part of the adventure. 🙂
