Vegas - book hotel last minute in location or in advance?

[mark387mw]

Plenty of advice on here re hotel and car hire recommendations but I can't find anything about booking ahead or booking last minute.

We're booked for a couple of days at the end of August, then we're free for a week with no car or hotel planned.
Can we book last minute and get a good deal on car and hotel, or by booking ahead are we getting the better deal.

I could do a dummy booking to check but I'm after real world experience.
Can we book on the day and get a deal of a lifetime or will Vegas be so busy you need to plan ahead to get somewhere decent?

Same for car hire, do they do better prices just by turning up on the day, or better to get a discount by getting a car sorted earlier?

Iirc you can book most hotels in advance and if a better rate comes along nearer the time they will match it if you ask them.

Some time ago, petrol stations had free voucher booklets - we used these as bargaining tools. Rocked up at a hotel/motel, asked for their best price, if cheaper than competitor's voucher price, accepted; if not showed voucher & instant price match.
