I am one of those people - after many, many years booking suites on Celebrity- we walked.
For example we booked a Crown Loft suite on RCCL Symphony next cruise. Less expensive than a Sky Suite on Celebrity by quite a lot. We get a number of suite perks including unlimited streaming WiFi, and meals at Coastal Kitchen (suite restaurant), but we would have to pay for a beverage package if we wanted one. And gratuities are not included on either line now. As we are D+, we can get drink coupons every day and access to the Diamond Lounge. Also drinks included for free in the Suite Lounge. This all works for us anyway.
