Hi, Joni! Great idea to clear out your memory card each night by uploading it to your computer. There is a charge at all the resorts for internet use (about $10 a day.)
If sending photos to family is your goal, you may have a way around it. Do you have any sort of mobile device? Granted, you could take some shots along the way and text/e-mail/post them to share with friends and family. However, you may also be able to share the photos you take with your higher quality camera by letting your mobile device function as a hard drive.
First, load your photos from your camera onto your computer. Next, select which pictures you'd like to share. Then, connect your mobile device to your computer and follow the prompts to let it function as a hard drive. In most cases, you can then drag the selected photos from the computer onto the mobile device. When finished, unmount the mobile device and then locate the pictures on it. You can then e-mail/tweet/post/text them out to everyone you want.
In the event you don't have a mobile device, I apologize for geeking out on you!
