HOTEL GRAND SHINONOME

We reserved a block of rooms in Hotel Grand Shinonome, a comfortable hotel in
the vicinity of Tsukuba Center. The hotel provides a free bus service to and
from the conference site. The prices quoted below include buffet-style
breakfast. Check-in is between 3 pm and midnight.

   price per room per night    

   single      8,000
     twin     14,000

-------------------------------------------------------------------------------

OTHER ACCOMMODATION

We also provide accommodation in the two guest-houses of the University of
Tsukuba, the Tsukuba Study and Training Center, and the guest-house of ETL.
Some of these places are within walking distance of the conference locations,
others are easily reached by (public) bus. The price depends on the room but
generally falls within the 1,000 - 4,000 range (per person per night). Some
of these places have shared toilet/bath and don't offer breakfast. Check-in
is between 4 and 11 pm.

-------------------------------------------------------------------------------

PAYMENT

Participants staying at Hotel Grand Shinonome can pay directly at the hotel
when checking out. The hotel accepts major credit cards. Participants staying
at the other places should be prepared to pay cash at the RTA98 registration
desk upon arrival; participants will be informed in advance of the exact
amount.
