domain Tourism related domain appraisal and another...Thanks!

Hello,

I would like your opinions on the following domains I registered:

reservetour.com
voidfun.com

The first is about reservation of tours but the word "reserve" also implies natural reserve tours...if I search the two words on google, it returns 9,090,000 results

The second came to my mind because of future entertainment companies offering extreme sport or adventures in space.
But it looks like a very sought after combo of words for the void function in C++ programming and others...

Thank you for your opinions...
