I'll be staying there for 2 nights on May 11th and 12th, so I'll be sure to write a report if one hasn't been posted by then.
Also, and I hope I'm not offending anyone by this, but as someone who has traveled around the Myrtle area a fair amount I would never ever consider using a GLON for a stay there unless I had way too many points than I knew what to do with. I personally can't stand Myrtle Beach, it's waaay to congested and touristy in the summer, the traffic is terrible, restaurants are packed, the beach is only so-so, etc. etc. etc. Your points would be much better spent on one of the wonderful hotels in Europe or Hawaii, but that's only my opinion.
