I like Marriott Residence Inn and Courtyard. But I am not fussy, as long as it's clean, in a safe neighborhood and has free Internet. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

That schematic was quite sobering :-) Early electric engineers assumed that the DC dynamo internal resistance should be the same as the load resistance for maximum power transfer and thus, thin wire was used to make the windings in the dynamo in order to increase the internal resistance. Soon they realized, that this does not make any sense and thick wires have been used ever since.

With the price of copper going up, the wires get thinner again, and the temperature rises :-)

It's been a couple of years since I've flown (too much hassle), but the biggies seemed to not be free (ORD, ATL, etc.). >>> Once I sat in the Irish Pub >>> next to gate C1 when connecting in Las Vegas.

I like Marriott Residence Inn and Courtyard. But I >am not fussy, as long as it's clean, in a safe neighborhood and has free >Internet. We've been staying in a Holiday In Express in the Atlanta area fairly frequently. It's a nice place, in a great location, and the price including Internet, has been about $60 a night (tax included). We started going up there to an Embassy Suits, but it wasn't a great hotel and they charged for everything, except cocktail hour (I don't drink) and breakfast. Internet was $13/day. ...and we travel with two laptops. With the economic downturn, hotel rates have gotten cheap, particularly weekends. We've found that HI Express has been cheaper than most decent places. Of course this doesn't apply to resorts. We were in a HI Express right on Orange Beach, AL a couple of weeks ago. Internet was included there, but it was $150 a night (off-season rates) before tax. It was supposed to go up to $250 a night about now. I wonder if that'll hold for the season. :-( |
