Pilgrims didn't stay in a hotel. The first ones had to build their own homes, roads, grow their own crops, etc. And after that there were the homesteaders. Rough life which wiped out many families. If the illegal aliens had to do even a fraction of that, they'd hightail it back to wherever they came from.

that's really the trick they are trying to pull.
The NGOs ship them 99% of the way and then let them walk a fraction so you think they've walked thousands of miles by foot.
99.99% of them will go back wherever if things get rough here. Many "good immigrants" from like china will do the same.
