I'd love to hear more about your trip. The idea of flying somewhere and renting a bike for track day or two really appeals.
I am terrible at writing reviews!
If you have any specific questions let me know but basically I booked with
http://www.tracksense.co.uk/ then bought a plane ticket and everything else was sorted for me by Track Sense!
Arrived on Monday, chilled for the afternoon with some other people who I met in the plane/airport. Laster that evening we drove from the hotel to the track to unload and setup in the pit lane garages.
Most people transport their own bikes on the track sense lorry, I think they have space for about 50 bikes. Others drive with vans and trailers (people come from all over and not just UK).
Since I had a hire bike I just signed the forms which were prearranged for me by Track Sense with BMW and rolled it round the garage where the guys I met earlier were setting up.
Track Sense provided me with paddock stands, tyre warmers and two sets of tyres, you can pick Pirelli, Metzeler, Dunlop or pay some extra and specify exactly what you want but since I am novice I just went for Supercorsa SP as they last well and have more than enough grip for me.
The bike comes with a tank of petrol and you return it with a full tank, I used one to two tanks per day which you have to pay for.
They also come around the garages and check on the hire bikes to make sure the tyres are looking good, adjust the pressures and generally make sure everything is going well for you, an excellent service!
The next three days (most events are 3 or 4 days at the track) are split up into sessions as normal track days are with novice, inter, fast and this time race groups.
Each bike has a transponder attached to it and there is a garage setup with live timings and full recording of every lap you do, the groups are the altered so people are with others around their own level. This is good so there is always some a bit faster to follow and you can improve but no crazy people going in the slower groups just to feel good about passing everyone!
There are also two "fun races" one for the race/fast and inter/novice which this time had a rolling start, 7 laps with a trophy and champagne for different groups and bike class (750 is a shoe in for a trophy as most are 600s or 1000+).
Then in the evening everyone is out and about in the bars, pubs and restaurants around the hotel area so plenty of good times to be had before it all starts again the next day!
I did Almeria in December, Valencia this week and now looking at the Slovakia Ring in June.
Like I said, any questions just ask!
