Yes, these wifi adapters do create their own wifi hotspot (so it's independent of an area's wifi hotspots: you can even run it in an area that doesn't have any wifi). Canon does recommend having another hotspot for laptops, to be able to go on the internet and make sure software is up to date....but the transfer of photos is done by the adapter's wifi. Chances are you'll also have made sure everything works before this event. Since you want to print straight out of camera, the W-E1 is a better value: it will be able to send the full res jpeg to the EOS utility software (and from there, your daughter can print). The main downside against this is that it takes up your SD slot and doesn't provide memory (so you have to save images to a CF card). 3rd party companies like Mobi and Eye-Fi offer SD wifi cards with memory. Camranger and Case Remote use the USB connection (and can offer some more features for remote shooting). IMO, if you're looking for downloading jpegs from your camera, the SD wifi cards should be fine.
