Here is some random, yet hopefully useful information and links about Tucson:

Conference Hotel: Four Points Sheraton is located at the intersection of Campbell Avenue and Speedway Boulevard, 1900 E Speedway Ave. Their phone number is 520-327-7341.
Mathematics Department is located to the South-West of the hotel, approximately in a 15-minute walking distance. There are campus maps available at the front desk, or you can use the Interactive Online Map. 

Getting to the Hotel from the Tucson International Airport: a taxi ride costs approximately $17. A cheaper, $1 alternative is to take a city bus number 6 to Speedway Boulevard and then walk East for about 15 minutes or change to number 4 or number 5. The bus schedule is available here.

Getting to the Hotel from the Phoenix International Airport: there is the Arizona Shuttle service, which operates once every hour. The closest stop is University, which is about 5-minute walk from the Department and a 20-minute walk from the Hotel. (Small map.) Please check their webpage for schedule and reservations.

The Visitor Guide to The University of Arizona has useful information regarding events, museums and exhibits, dining opportunities on and around campus. At the registration you will also receive a folder with some useful information and maps. [There is a good breakfast-coffee place, Bentley's, one short block West of the Hotel, next to a 7-11.]

The Banquet: on Saturday at 7pm, at the Old Peking Restaurant, 2522 E Speedway Boulevard, intersection with Tucson Avenue, a 10-minute walk East of the Hotel. If you did not sign up for the banquet on your registration form, and are willing to attend, or bringing an extra person, please let us know. The banquet fee is $25 and is paid at the registration. The banquet will be buffet style and include: eggrolls, crab puffs, honey walnut shrimp, roasted duck, green mussel with black bean sauce, sesame chicken, broccoli beef, sweet and sour pork, as well as vegetarian dishes: bean curd with vegetables, string bean in szechwan sauce, vegetable fried rice (no egg), vegetable lo mein.

Internet access: there is a computer room in the Math Building, there is also free Internet at the Hotel (if you bring your own laptop), our Main and Science libraries also have many computers available for public use.

Weather: is expected to be mild, so visitors need not fear the desert's extreme heat. Temperature during the day is most likely to stay in the mid 70s to 80s, with cooling down during the night by ~20 degrees. Rains are unlikely.
