We travelled over in September. Our top tips:
1. Make sure you physically see the paperwork before you sign for your hire car and that the balance says $0.
2. Take thermos flasks to the parks with squeezy cordial. Ask for cups of iced water and make your own juice up - 500ml drinks are in the $4-5 region so we saved a fortune.
3. Buy waterproof macs before you go. We got ours for around £6 from Decathlon and they were perfect.
4. Take two pairs of comfy, worn in shoes to swap out in case one pair gets soaked through.
5. Mains are generous in size - we found sharing one and ordering extra sides worked well for us.
6. Loads of shops offer discounts for signing up. If you know you'll visit certain shops, sign up before you go.
7. Likewise, loads of restaurants offer freebies for signing up. I'd recommend doing this before you go and screenshotting any offers you get through.
8. Magicbands aren't required. Lanyards work a treat and we found were cheapest at Walmart, loads of designs available.
9. A pack of microfibre cloths work a treat. Add iced water for cooling off in the heat or use dry ones for drying off if you get caught in a storm, or after a wet ride!
10. Bumbags! I'd have been lost without mine. Fashion doesn't matter over there.
I'm sure I'll be back when I think of more but happy to answer any specific questions anyone has.
