I'm so sorry for you during this hard time.
But I do want to say that I wouldn't think twice about sneaking your kitty into a hotel. I drove from NYC to LA and back a few years ago with my then 19-year old Fred in the car and we snuck into many a hotel--with subQ fluids even-(pain in the ass to lug all his supplies, but I did what I had to do)
I just recently snuck 2 cats into a hotel in Ithaca NY. Cats are harder to detect than a dog. You just have to be careful with the carrying in and out, make sure the cat doesn't meow if you're on the elevator with a cleaning lady or something.
Also, in respect for allergic people, one thing I do do is put towels on the chair in the hotel room, so if kitty sits on it, it won't get allergens on there (although trutfhully, our cats on their appropriate diets should not be making others allergic because they themselves are not having allergic reactions). Also if you bring his kitty bed, if he has one, he would prefer to sit on that anyway.
My Fred was Burmese--so a loud meower--when I would leave the hotel room I would turn on CNN quite loud so that if anyone walking by heard him it would be muffled by news!
I recently bought this great litter box at Petco that was perfect for the car and the hotel room. It had a hole ON TOP...and therefore a lot less spillage of litter...and also in the car, no fear of tipping it over and you could strap it into the seatbelt in the back seat.... IT was actually this one of the right in the photo on this link:

So the only thing you have to do is make sure you clean up the litter after you leave. So make sure to put it into the bathroom where there is tile, not carpet. And this top entry litter box leaves very little spillage. Make sure to bring a scooper and also one of those teeny little dustpan/brush sets so you can quickly/easily clean up spilled litter.
If you get caught for some reason, then just say you have an elderly diabetic special needs cat...the worst they will do is fine you. I think what they are worried about is destruction by an animal--peeing all over the place, loud barking, etc.
good luck.
