More suggestions:
Make sure you ask for any possible discount rates that may apply to
you and your family. In my checking, the lowest rates seem to be for
Internet booking, aaa members or seniors, then followed by those with
government/military ids. so if you have don’t have a aaa card but
grandpa (or over 50s) with you, make the reservation in his name.
One hotel which kept coming up as a low rate was:
Suburban Extended Stay Hilton Head
1376 Fording Island Road
Bluffton, sc, us, 29910
