We are going to DW in July but not able to book our trip until Mid-March. There will be 8 of us so we would like adjoining rooms probably at CBR. My question is since we can't book until later should I go ahead and reserve 2 rooms now and then add tickets/airfare on in March? Also, I heard that requesting adjoining rooms doesn't really mean much that you just have to hope you get them when you check in.
