I am a solo traveler, by choice, and when I saw that Regent was offering a 25% single supplement, I called my wonderful travel agency and inquired. I also learned that there were discounted business/1st class air accommodations if I wanted to pay for the upgrade. I did and was very pleased that I did.
Flights were smooth, pickup in Venice, Italy was simple. Off to the ship. Spent about an hour being wined and dined as the last touches on my suite (890--a great balcony suite) were being attended to.
Met my two (2) stewards: Nelma and Dinesh. Gave them each a couple of extra buck$ and asked them just to look out for me. And they did My suite was attended to each and every time I ventured out, whether for food, a walk, or an excursion. I never knew they were there but could tell when I returned to my suite.
Absolutely fantastic in every which way!
