Ok so April 11-13 is looking promising? Agreed that movement toward a group plan or booking might be helpful.

Nice to earn or burn points on the hotel but happy for those of you who know/care more about hotels to decide for me

If there are events at the airport, then the IC Doral might be a good value as it's $135 per night at the moment (via AAA or advance purchase). Perhaps they might offer an even better group rate, which might be hard to beat for a 4-5 star property?
