Let me preface this with I have never purchased a ticket to the tent since it started in 07. I think that in 07 it was prabably not a bad deal cost wise or with the crowd in the tent. However, leave it to the Mouse to ruin a decent thing. The tent is now open to ChEAR squate Platinum folks, also. I heard that last year the floor space was nil with the added load. The lines in the tent were not all that short either and the food stuff stocks were non-existant. Again, I have only peered into the tent.
Only one in four or five events is honestly cold. The remainder are cool but easily managed. Head to
WalMart and purchase a cuople flannel warm ups for use on race day. Cut the legs up from the bottom hem about 6-12 inches so you can remove your foot with shoes on. You can wear these as long as needed, discarding them at the start line if needed.
Add a trash can sack (large black ones) with a hole in the bottom for your head and one on either side for arms and you have a wind/rain breaker. You can also pruchase a Tyvek painter suit (Some years at the expo also) that serves to break the wind and can still be ripped off.
Finally, don't tell anyone but if you go through the baggage claim tents when you first arrive at the gathering area on race morning (you do not have to leave a bag that early) you will find about 75% of all porta potties in central Florida lined up with few folks waiting. Obviously this area will start to crowd up as race time nears and lines will form. once that occurs, the lines for the potties outside of the baggage drop area do not have much of a line. This may be tmi, but in a dire need, the trash sack can also serve as a shelter for the same busuness.
I guess this is a long winded answer saying that the tent is a luxury. I swear that if the temps are in the 30's race day morning I will be the first to say the tent would be a great deal. We are due a cooler race this year but if you prepare it's just not all that bad. Besides, 17000 of the 20000 runners will be outside.
EDIT - For the nerves, if you need chill out space, there are sveral little nooks you can plop down at and chill out.
