Waterside is the best choice....very close to Coligny Plaza where you'll find shops and restaurants, and a few blocks from New Orleans Rd which has several top-notch fine dining restaurants. At the end of Pope Ave & around Greenwood Circle, there are 4 or 5 more restaurants.
Also close to Sea Pines and Harbour Town where there's more of the same...easily bikeable to Sea Pines bike paths, best on island.
Three grocery stores close by.....Harris Teeter & Publix......also a walkable Piggly Wiggly in Coligny Plaza (not as great as others, but convenient).
We own two 3BR villas at Waterside, and enjoy it a lot as "extra Hilton Head time" in addition to our 8 HH Marriott weeks
(believe me, it's never enough), and
just returned from Waterside yesterday. Had a great time.
IMHO, one of the best non-Marriotts on HH.
ALL of the villas at Waterside have been renovated within the past year, and very nicely, too---
in fact they're beautiful and quite comfortable.
The 3BR units (typically on both ends of buildings) are large and bright, and each BR has a full bathroom, so 3 nice bathrooms.
Two master suites with Kings, 3rd room has 2 Twins.
Large LR & dining area......many have very nice balcony views, wooded or lagoon.
Under-building parking, as "first floor villas" are on second level.
