Just 100 yards East of there is Cocoview. If you liked FIBR, you'll think CCV is heaven.
AI Resorts? On Roatan, there is also AKR (Anthonys Key), Reef House Resort (RHR), and BFK (Barefoot Key). Somewhere less well regarded is Turquoise Bay (TBR) and Media Luna (MLR) which are more of resorts that offer diving. In that same category are some other operations which have a small but fervent following here, Henry Morgan (HMR) is included. All "AI's" are not necessarily dive resorts. Some HMR guests may do 2 dives a day, most/many do 1 a day, in that range. Not all that many guests are divers. The place is pretty inviting. Why leave?
Your criteria becomes hugely flexible and quite vague due to your wording- ("a nice all inclusive resort preferably with a dive op on site.....not required just handy") either you want what an on-prem AI Dive Resort offers, or you are willing to shape the dive portion of your vacation by what the resort can/will offer.
Your experience at FI might have been at its peak of quality and service a few years back, or it might have been in its troubled times. The rooms and food were never reliable, but (a few of) their stellar DMs dedication spectacularly overcame even their dive op's dismal infrastructure. They were by no means u/w naturalists, but in every other respect, they were the perfect DMs. The DMs made people rave about the place, and no-one really understood that they kept the place alive. Your experience there was "good", but it depends upon what you really wanted.
If you want the ultimate Roatan dive-centric vacation, it's CCV with an easy 5x a day. However, the other AI Dive Resort properties I mentioned above offer varying quantity of diving access with a known and stable level of service- some of it is up-scale by Roatan standards, but whatever you chose, 3 Star is about tops for Roatan. The place is pretty provincial in terms of aspirations and ability to deliver the "luxury" experience.
You were on the South side, and that dive environment is unique. You will not find that near the North (TBR) or the West (HMR or AKR). AKR has the wherewithal to move dive operations to the South shore if weather shuts down North/West as it is wont to do August thru February.
