Hotel Welcome Basket question

So we have 20 rooms booked at the Fox Hollow for the night of the wedding, but about 4 or 5 more couples couldnt get into the hotel right away due to other blocks at that hotel. I told the couples that they should just go on the wait list, and rooms will open up a month before the wedding. These other people ended up booking at 2 other hotels nearby - the marriot and the best western.

I'm providing 20 hotel baskets for the guests in the Fox Hollow... they also get shuttle service, as well as brunch in the morning. Am I obligated to also bring baskets to these two other hotels? I just wonder because they are the ones who decided not to stay at the hotel where we blocked rooms.

And what if other people that i dont know about are staying in that hotel. how do i find this out?

Or do i just leave it alone because they booked elsewhere?

I didn't

I just left our bags at the Fairfield.....and the idiots at the fromt desk didn't even give them to everyone on our block
