Honeywell makes a set of audible alarms that work well for about $10.00 for a box of 4. (You will just have to remember to turn them off before the staff cmes in to clean.) Not sure if you have a store called Big Lots, of possibly a Walgreens. They work very well, and will give you added comfort during your stay. I use them every year, but don't really need them. OCD...They are easy to put up, and take down.
