I too thought the room service menu was going to be expanded. All Carnival has really done is add additional charges. Last time we cruised on the Mardi Gras, the room service was the worst we have ever had. We don't order much but the items we did order, which had an additional charge, were just awful. The last cruise we skipped the main dining room every night and ate mostly at the specialty restaurants. We paid for them because the food is so much better.
Years ago, when we first started cruising, all your food was included, and it was good. I know the cruise industry took a big hit during Covid, but we are still paying for our cruises.
