We just go back from HHI....yes, bike rentals at the resort are $20 for a day or $35 for length of stay. Patriot was very easy to work with, I called early Sunday morning to let them know that I was at the resort(I had reserved bikes the week before) and ready for delivery and they show within 45 minutes and dropped off the bikes, locks, baskets, no problem. I asked and was told to leave the bikes lock up in front of our building and they would come by and pick them up on our departure day.
The bikes look very new and were your typical cruiser one speed bike. The Disney rental bikes were bascially the same style with maybe a little wider seat and foam padding on the handle bars versus the bikes from Patriot.
One thing I did notice was the number to call if I incountered a problem was different than Patriot's main number and the delivery man told me, the owner of the company had six different locations on the island under different names and that was the number to call if we needed service....interesting.
There were plenty of bike racks on property...each building had at least one and serveral racks were located at the pool area.
We did ride to the beach house on our first day there and made several other little trips around, but we did not ride nearly as much as I thought we would.
Also, I do recommend the Sea Shack for seafood, if you have to wait in line, it is worth it (we ate there twice). I do recommend, One Hot Mama, good BBQ and fried chicken. We also ate at Kingfisher', just across the bridge from the resort which was nice also.
We also went to Savannah on the last day of our trip, I wish we would have went earlier in the week, we would have went again. We had lunch at Mrs. Wilkes, which I highly recommend. A line form early, it would not hurt to get there around 10:15 to get in line. Also, we took the Old Savannah tour bus around town and learned alot about the history of the city.
