Just booked a voyage for later this year on Silversea's new Silver Nova from Lisbon to Barcelona. This voyage was originally a 17-day cruise, but they just opened up two options to book this for a shorter version.
This will be my seventh cruise with Silversea (last year I was on the Spirit for a voyage with 5 ports in Croatia). Portugal has been #1 on my travel bucket list (was supposed to go in 2020...), so very much looking forward to the itinerary and the opportunity to check out the new ship design.
