if you're somewhat close to the beach or a bay, you can sign up for a group deep sea fishing charter. Thats what a friend of mine wanted to do during the day for his. Im not a big fisherman at all and we did this and I still had a blast, nothing beats drinks on a boat on a beautiful day.
We did the deep sea charter, came back and changed, then went out to eat then did the night out.
.....and you can have a great bachelor party without dancers. Ive had more fun at bachelor parties without dancers than ive had with them. If your buddy wants dancers though, then you might wanna make arrangements, if he doesnt, then I'd listen. Ive seen someone get real mad after someone ordered strippers after he asked them not to.
