Share 'Nice to Cap d'Agde'

I had posted a question wondering if  Cap d'Agde is a reasonable day trip via train from Nice?  Just as a follow-up for future reference to anyone else that maybe curious in the future, it is a 5.5 hour train trip connecting through Montpellier St-Roch and is at current date $104 RT per person.  Too far for us on this trip.  I wish I would have checked into it sooner and planned a overnight trip…
