I didn't put down any instructions except my reservation number. They hold it at Bell Services and refrigerate anything that requires it. They call you from Bell Services but keep an eye on your message light. The hotel staff brought up our order which is great because I had purchased 24 bottles of water. I tipped the hotel staff member for bringing up my order.
I didn't tip the Vons delivery person because I wasn't around... and even if I was, they just drop it off. I thought I read somewhere here that they do not accept tips or perhaps that was on Vons' website?
I was able to hit $49 for free delivery even though one of my items was out of stock so it was less than $49 but still no delivery charge. Of course, we are here for the week so $49 was easy. Also, the groceries here are cheaper relative to back home in Canada so more than happy to purchase the groceries here.
