    <p>To place a bid, a future dated Brooklands Hotel room reservation number is required. </p>
    <p>Only bids placed before 3pm the day before arrival are valid.</p>
    <p>The form must be completed with all requested information.</p>
    <p>The placed bid must be equal to or more than the stated minimum bidding amount shown.</p>
    <p>The minimum bid is the lowest bid the Brooklands Hotel will accept.</p>
    <p>The maximum bid shown is the full upgrade price.</p>
    <p>The pre-booked room type and upgraded room type requested must be selected.</p>
    <p>The minimum and maximum bids shown vary depending on your pre-booked room selection and the selected room type to bid on.</p>
    <p>By submitting a bid a contractual commitment is made to purchase the selected upgrade at the price bid, to the Brooklands Hotel, should this be a winning bid.</p>
    <p>The placed bid will be sent directly to the Make Your Day team.</p>
    <p>At 3pm the day prior to the pre-booked reservation arrival date, all bids for this arrival day will be collated.</p>
    <p>The highest submitted bid for the arrival day will win the upgraded room.</p>
    <p>All bidders will be notified on arrival if their bid is the winning bid.</p>
    <p>Bids are supplements and will be charged in addition to the pre-book room reservation room rate, for example:<br />
        If you booked a Deluxe room at a rate of £139 and place a bid of £24 to upgrade to an Executive Room and this is a winning bid (notified upon check-in), the £35 upgrade fee will be added to your pre-booked room rate of £139. Therefore you total room rate bill will be £174.</p>
    <p>All rooms and upgrades are subject to availability.</p>
