I've taken a toaster oven to
Disneyland (drove & stayed offsite) and a regular toaster to San Fransisco (flew), We have a little 2 slicer I got for under $10 at
Walmart. I call it my 'travel toaster' We've taken it to Vancouver a few times too.
I unplug it when not in use and TBH if I thought it 'wasn't allowed' I would just tuck it away after use. But I guess I'm just not fazed by random rules ( sorry a toaster that's only plugged in when in use is no more of a fire hazard than a coffee maker or a power bar charging 5 devices overnight or an iron that is accidently left plugged in when you leave the room.)
And I can't see how I could burn toast bad enough that smoke alarms would be going off when I am standing there making the toast.
We loved our toaster not just for breakies but bedtime snacks.
My kids happily eat a cold breakfast but it's not something I want to do for 5-10 days
I know by the tone of this thread I am going to get pounced on, but I also know that most people on internet boards act a lot more righteous in print than they act IRL.
