Vaguely looking at a cruise for early July (after DS's GCSEs). Possibly just me and him (16). Would there be stuff for him to do on board at that time? What are cabins like to share (not that comfortable sharing with a 16 year old boy but I guess it's cheaper than two cabins!). Just looking at maybe a week in the Med on a MSC Cruise as someone said these were quite good value for money but happy to take other advice. I've never done a cruise before so any advice would be good in fact! Thanks.
