Agreed... My particular experience is with what i would consider "medium" size convention-like events (national gymnastic meets) in mostly "secondary" cities -San Diego, Milwaukee, Cleveland, Savannah, Minneapolis, Fort Worth, Corpus Christi, Nashville (no offense Leo)... It has worked well for me with two different approaches. I know when the cut-off date is for the "official" block of rooms is at the official hotels (usually 2-4 hotels connected to or nearby the events). Cut-off normally is about 2-3 weeks in advance of the meets. Up until that time, I usually don't have the greatest success in getting historically low bids. Once the block is released though, I can normally do at least as well as other posters have reported. However, in several instances, I make use of my "way early bidding" strategies. (like 3-6 months and once, even 11 months in advance!!... really!), using my coveted, patented, copyrighted (am I usually this obnoxious??) RLB TACTICAL approach... Ridiculously Low Bidding, that is... It helps of course, to know the event dates way, way in advance.... and to have a son for whom you have a full confidence in his athletic abilities (in order to qualify to compete at those meets!) RLB has me going for 4* first, but I often lapse into the 3* arena rather quickly (usually ending up 25-50ish% less than 4*- based on actual posted "wins")- with which I have almost always been perfectly happy! But, seriously, I think that nearly every "win" I have, has beaten (or lately, equaled) the lowest reported win posted, using one or the other strategy... :)
