Not sure if this still applies, but in Fall 2021 the exterior entry rooms were getting some refurbishments done. Also, the pool on that side was only open Friday-Sunday (if I recall correctly). Other side of the hotel, with the lazy river, was open daily, but a bit of a hike from the North End of the Resort.
If anyone's stayed there more recently, they could probably confirm if this is still the case. Imagine it had more to do with staffing than it did Covid regulations.
