Was on the Navigator 4 niter last week. The ship is beautiful she just came out of dry dock.
All the activities that are found on a 7 niter were on the Navigator.
Belly Flop competition, Men's Sexy legs, poolside line dancing, great poolside band, Great 6 piece band in the viking crown lounge, wonderful staff, Excellent latin band, One of Royal's best DJ's - DJ Anthony, 70's party, 2 promenade parades, Trivia, Bingo, love and marriage game show, good production shows, comedy show and midnight comedy show, Rock a roke (Karaoke with a live band), Dancing under the Stars, Club 20, The Quest, very very very good ice show (the Abba part was great), Ice skating and rock climbing, basketball and soccer.
I'm looking into the Navigator 4 niter once again in December. It is an excellent little cruise at a reasonable rate.
I'm sure you would enjoy the Navigator.
