Grocery Stop MCO - Royal Pacific

So I have booked a 3-way transfer using Quicksilver Tours Orlando that includes a free grocery stop. Wondering where the best place to stop would be. I was thinking that I would shop while DH gets himself and the 3 kids something to eat while I am shopping (there is nothing worse that shopping with 3 kids and a husband who are hungry). Thus, a cafe in the store would be a great help!! I see that there is a SAM"S club in Orlando and we are members and frequent our club at home. Plus I am familiar with the layout and items sold. I have heard great things about Publix as well, just never have been to one. We are arriving at MCO around 5:30pm on a Tuesday if that makes a difference. We will have 45 minutes max to shop. Thank you in advance for tips:)
