I'll be in Gold Coast from May 7 2014 to May 13 2014 with my wife and my daughters (4 years old & 2 years old). After browsing the net, I found out that May is neither peak nor low season. So in order to plan things accordingly and perfectly, since I've never been to Australia before, I'd like to know (in the month of May):
1) Which is the most crowded and least crowded beach?
2) Which beach is the safest for my kids to swim?
3) Are the attractions (Movie World, Sea World, Currumbin Wildlife Park, Skypoint) crowded?
4) Will I get a rental car if I go straight to the counter without booking online (hopefully to get a discount because it's not peak season)?
5) Does it always rain?
6) Traffic condition?
Just for the record, I am not claustrophobic or agoraphobic, it's just that the lesser the crowd the merrier my family would be (more chances for us to experience things without the long queues).
