If it's just a hotel you do not want to go to, be prepared to help with the upgraded rental fee.  I'd let her know your concerns, and  see how she reacts first.

And if you would cover the added expense, she will appreciate it very much..Sometimes, I guess providers just book a hotel due to the price but not necessarily due to safety or comfort (I guess it depends on her rate as well). Safe Office is a great resource for us, maybe you should suggest she signs up.

All taken care of. Feel much better knowing the lovely lady is going to be in a safe area.

to seek opinions of locals as to where to stay for her safety and convenience to primary market area for hobbyists.

Any idiot can research a hotel before arriving and know by the star rating or the area rating, if it's a go or a no. I've only been duped a couple of times, but it had more to do with construction that was not reported. If you hired a high end gal, paid a deposit, etc. she should have better sense. Sorry, but even if you are totally new to an area, you still have the means to research before you book. Even hotels.com will give you hundreds of reviews about said hotels, star rating, neighborhood average, hidden charges, if there is a key card required, etc. There is simply no reason not to do the work for a date such as this.
