We just got off Solstice on Boxing Day. Regarding trivias, there are 3 to 4 of them per day and a ton of fun and usually held on deck 14 in the Sky Lounge. Dee, young girl from Brazil, and Dennis, young Filipino man, usually run those. Dennis, especially, is a ton of fun. There is also something very silly with audience participation every night at 8pm and not to be missed, on deck 4.
Out of the 7 nights, Celebrity Production singers had 4 nights - BOO, I always skip them because they are really not good singers. Normally, we only get 1 night or maximum 2 nights on a weeklong cruise. The other 3 nights, we had a Canadian lady comedian, well she was a little over the top and I thought she was OK but my husband didn't care for her. We had a very good high energy threesome called Uptown and they were fabulous. They did a bunch of Motown music. We also had a magician and mentalist called Andrew Lee from Malaysia and he was top notch. He performed on night 6 in the theatre and also night 7 in a smaller room called Celebrity Centrale. He was a semi-finalist in Britain's Got Talent and an Asian version of that. He was also on America's Got Talent or some version of that. The response was overwhelming and Celebrity Centrale barely had any standing room left to see him on night 7.
We enjoyed Sushi on Five and had a lunch and a dinner there but did not do other speciality dining venues.
Enjoy your time. Penthouse Suite sounds fabulous!
