SD card- any picture stations 2 transfer??

[2diamonds&a~gem]

I have 2 SD cards that will hold about 100- 125 pic's each, I am planning on bringing my moms SD card too, so I will have 300-375 pic's. But this will not be enough. I take 10 or so pics a day on a regular basis here at home and I just know that I will need to transfer the pics somehow so I can take more. (Bit of a picture hound) I do not want to buy another larger card for the trip. I was hoping to find a Do It yourself ATM like thingy (think like what they have a walgreens & walmart) so I can get the pics transfered to a CD. I have been four times in the past 3 years, but I have never needed one before so I cant seem to place it, KWIM? We always had a car before so I used the one @ Walgreens, but we arent getting a car this time. And sadly we will not have our new laptop until after we get back. Please help!

TIA!
