Thank you all so much for your replies. Buckeye Mark, that Aeropress looks fantastic. I'm in New Zealand & don't think I've ever seen one, but you can bet that I am going looking for one now (not for the cruise, but just because it looks like something I would use). Mdpseattle - Starbucks do instant sachets?? Wow we are really missing out down here in NZ...I am on the hunt for those too. You all have no idea how much I want a Costco in NZ!!!!
Sending my sister for coffee would go down wonderfully (ha ha) - she doesn't drink hot drinks so she would probably arrive back with a Danish!.
