Caravanistan

We took the bus in August from Bishkek to Tashkent. Departure in Bishkek is the Western bus station. We arrived in Tashkent in the bus terminal (at the Niyat hotel).
It is a long and not very comfortable ride. Especially the border crossings prevent you from sleeping. But it is relatively fast. Don't expect a bus with the same standards as on their website

Anyone know if this is likely to be running as usual during Nowruz, and if tickets can still be easily bought a few days before departure? Planning to go Tashkent-Bishkek.
