We choose this cruise because the last Solstice trip (to Sth Pacific) the average age was around 60, still way older than us but ok. This time is very around mid 80s and most people were not mobile. Getting around the ship was very frustrating and the music on board was obviously to cater for them - 30s and 40's (which my husband and I can't stand).
We don't have children (by choice, they annoy me); so it was good that there weren't too many to be seen or heard.
The ports were mostly good but I would get rid of Lautoka and Suva and try and use a beautiful outer Fijian island. I've been to Fiji a few times and the ports are not a true reflection of the beauty of the Fiji.
