Thanks to all, especially the info on the Divani Caravelle. I have stayed at the Grande Bretagne in the past, and at the Hilton too. Like the location of the former more than the latter. Hotels were both OK but the décor of the GB is a bit "early brothel" for my taste!!
On Splendor we are in a Grand Suite and Regent says boarding at 1200 with access to suite at 1300. So I would like to get to the port early and will probably take a taxi. Really appreciated the info on the assigned bus numbers and the melée to get on the bus!
