Thanks for the feedback all. Tim and Sasdasdaf - Liberty Wreck before breakfast is probably the way to go - me, I'm partial to drinking coffee in the early morning tropical sun before getting in the water Two of my group did a late afternoon dive and seemed to have the wreck to themselves. Two of us opted for the Coral Garden shore dive - it was a tough choice which in itself is a good sign.
Paul, Lucky you, you should be able to get some really good diving in in 5 days, look forward to hearing about it when you get back.
Thanks Steve, the website is a bit behind now - I have 3 trip reports in draft.
