We've been twice, once when my boys were 3 1/2 and almost 6 and again when they were 12 and 14. All I ever took anywhere once they were potty trained at 2 1/2 was a fanny pack with tickets, camera, sunglasses, sunscreen and money. My DH had his wallet. It's a heck of a lot easier to buy snacks, etc than cart that stuff around. We were also on a tight budget, we just didnt' buy them everything they asked for and we ate a lot of counter service meals which for kids is the most economical. The fact is, most people don't need 90% of the stuff they haul with them. We also didn't use a stroller anywhere past the age of about 2. They walked everywhere and we never had a problem. I didn't want to add to the traffic jams and can't stand getting run into by kamikaze stroller parents. No one took naps, we just made sure to get them into bed by 9 each night and they were raring to go the next day. It just made our vacations extremely relaxing to just basically get up, shower, eat breakfast and go. No packing anything, hauling a stroller around or renting one, or worrying that something was forgotten.
