Jan and Fred, Seabourn internet is like Regent internet. Some of the time it is slow and other times it is not an issue. We buy the unlimited plan for $399 which lasts for however long your cruise lasts so, for you, it would be 40 days. I just add it in to the cost when I work out the cost of a Seabourn cruise. As this is your first Seabourn cruise, you should have a $400 referral credit. On our first cruise, we used it to pay the internet fees.
We have found the Seabourn shore excursions to usually be excellent. We just got off a 25 night Seabourn Pride cruise from Rome to Dubai and, with the exception of one shore excursion, all of them were excellent.
Have a fabulous time. I look forward to reading your posts whenever you have time to make them.
