The plan is to stay at Sanibel Island for shelling and then to leave around midday to head to next destination of Weeki Wachee. I noticed that around Venice would be a good place to stop and maybe we could look for sharks teeth.
How likely are we to find any? With 4 kids and two autistic I wouldn’t want to get their hopes up unless it’s fairly likely. Is the time of day important? I’m guessing we would be in the area from 2pm to sunset.
Is there much else to do in that area? Nice family restaurants?
Thanks for any advice
