We were on this cruise last week. This is a chartered cruise by StarVista they have 6 types of cruises, week before ours was 60's flower power, they also have country, oldies , disco and soul cruises. This costs more that most cruises but we thought it was worth the money. One of the main things we like about cruises is all the live music and this certainly had that. Michael McDonald, STXT, Air Supply, America , BJ Thomas , Poco , Guess Who and others. Lots of great cover bands were also there groups like War played at the pool. What we also found very interesting was the interviews , all the major artist had a interview that you could attend followed by a autograph session, I had some old albums signed, some people had there guitars signed. Interviews were extremely interesting telling how groups were formed stories about being produced by George Harrison or performing at concert for Bangladesh. These charters are very popular and many book it every year, we wanted to book flower power for 2019 and all the suites were sold out even though they just went on sale previous week. We did book sky suite for 2019 , this was 5 day cruise , I believe all the others were 7 days. Had not sailed on Summit before and liked ship and really liked the suite perks of private dinning room and suite lounge which had free drinks all day. These cruises are non cancelable so we booked insurance just in case.
