So my future mother-in-law lives in a private gated community in Hilton Head Island, SC right off the beach. She offered to let us use her condo and stay up near where we live with her daughter while we are at her house. We wouldn't have to pay for anything and she said we can even use her car to make any day trips we want. I like that we wouldn't have to pay but I am a little freaked out by the fact that we would have to sleep in her bed. Is the awkwardness of that worth it or should we just go on the $1200 cruise to the Caribbean? Budget is important because we are paying for almost everything ourselves. Help?
