you can bring those TWO bags...but the contents of at least one of them is going to go home with you unused! unless you're determined to stand out from the rest of your fellow tourists!
i wore a bathing suit with a few sarongs almost every day. wore the sarongs as dresses for evening dining. flip flops or slide on sandals the only footwear you'll need. all the clothing i needed could have fit in a carry-on!
it's way more casual on AC than you realize.
