We plan to stay at the Airport Marriott, then take their van to Tung Chung. From there, we want to take the cable car. Questions:

1. Is there a place to store our luggage at Tung Chung MTR or do we need to leave it at the Marriott?
2. There are remarks in this thread about the cable car not running due to wind. How often does that happen?
3. A friend recommends buying tickets in advance. He stood in line on a week day for 1 1/2 hours to buy his tickets. If we buy in advance, can we get them refunded if the cable car isn't running?
4. Their website for advanced purchase is currently down. Does anyone know if that has been ongoing or if it is likely to be up again in a day or two? The alternative is to download a form to fill out and email them. The form doesn't request a credit card number, so I'm a bit perplexed as to its helpfulness.
