Seconding CoachP -- a midrange solution would be for you to attend the meet but then see if she can sleep with another family and attend the college meet with her teammates. We do that sort of thing all the time. The kids are usually really happy to get to spend more unstructured time together. We carpool to a lot of meets, too, which saves on expenses.
It sounds like you know this already, but for anyone who hasn't thought about it, always be sure to check customer reviews before booking a hotel, even if it is a chain. You can sometimes find some unanticipated bargains that are much nicer than you'd expect for the brand (yay for my favorite Super 8!) and some that are awful or have major issues with some services (Holiday Inn near that meet venue we have to hit twice every season, I am looking right at your food service folks!).
