Cannot predict whether you can get a like deal this year. It just depends on what US Airways decides to offer as discount rates which to a significant extent simply depends on how full they think the planes will be if they don't go that low. US Airways has had some fairly good deals from a number of places this year so far. If you see a respectable rate before July, though not as low, I would probably take it rather than pin my hopes on a last minute drop in rates. National Car is actually located in a central location on the road to MK but you can order from any hotel. I do not know how many days you want to rent a car for but you should note that you can often get a weekly rental in advance with pick up at the airport that is actually cheaper than renting for 3 days or more while on site.
