Is there a church nearby on Sundays and is there transportation available for this?

I dont recall having seen a hotel shuttle when I was there in the Summer, but there are several churches within a 5 mile radius.

There are several churches within a 5 mile radius. The Bahia Resort Hotel does not offer shuttle service. There are several taxi companies and ride-sharing services such as Uber and Lyft available.

They don't have shuttle, and there's a church on old town. Not far from the hotel
