We travel with 6 adults (me, my hubby, his parents, his sister and her husband) and 2 children (our son and his sister's daughter). We get a 4 bedroom 3 bathroom condo and have plenty of room!
Do NOT rent through Grand Strand Vacations! Their customer service is terrible! I do recommend CondoWorld!
The last 2 times we've gone we've stayed at Windy Hill Dunes (North Myrtle Beach) which has a kiddie pool, regular pool, hot tub and lazy river, PLUS its right on the beach!
Also, if you want to go to any shows while you're there, call this guy: ###-###-####. He can get you discounted tickets and restaurant vouchers. We got tickets to the Dixie Stampede through him last year for 1/2 the price (he does works for many of the venues and they give him vouchers as payment, which he turns around and sells. I went into the Carolina Opry with him when he got the tickets so I knew they were legit)
Feel free to send me a private message if you have any more questions!
