We're (my husband, 14 year old son and me)leaving for Aruba on Monday (our first time there). We're trying to decide how much cash to take. So far, we've decided to take $250 in five dollar bills and $50 in one dollar bills for tipping. We've already paid for and reserved a couple of activities. Our lodging is paid for with hotel points. We're staying 6 nights. We won't be visiting any casinos. How much cash do we need and which places don't take credit cards?
