Currently all interstate buses stop at their respective companies’ pools ("terminal"). If you take an interstate or international bus to/from Phnom Penh, your bus company usually picks you up at your hotel from one hour to 30 minutes prior to your departure time.
Arriving in Phnom Penh from other towns, Tuk-tuks are normally also available around these bus pools to drop you off anywhere around the town, alternatively your hotel should be able to arrange a pick up for you.
Bus is a good option to reach Siem Reap from Phnom Penh and vice versa. Starting price is around US$ 5 for an air-conditioned bus without toilet, and around $ 6 for the one equipped with a lavatory, including a light snack and a small glass of mineral water. Normally it takes around 6 hours to reach Siem Reap from Phnom Penh and vice versa. Nowadays road conditions are generally good. Buses from Phnom Penh stop at a terminal located just on the edge of Siem Reap city. More info on public transportation to Siem Reap from Phnom Penh, Cambdia.
Travelers have also another option of reaching Phnom Penh or Siem Reap slightly faster, about 30 minutes to 60 minutes faster than the normal buses. The so-called "Ford minivan" that accommodates up to 15 people is the option at a cost of around $ 9. It may stop at a restaurant in Kampong Thom for a 20-minute break, though travellers might be told that it would be a non-stop journey. If you choose to take the minivan, unless you like enjoying a bumpy ride, you should avoid the most aft seats and if you need more space for your legs, don't take the window seat at this most aft row because the minivan's wheels take up a bit of the space.
There are also buses to Thailand (about 12 hours journey to Bangkok) and Ho Chi Minh City (Saigon, about a 6 hour trip). Prices really vary depending on bus companies and travel agents, which range from $ 10 for Saigon bound buses to $ 15 for Bangkok bound buses.
Usually, bus services to overseas destinations leave Phnom Penh early in the morning at 6:30am, while bus services to Siem Reap and other towns leave a few times day and night. Tickets can be purchased from either any travel agent through out the city (sometimes they might charge you an additional fee of US$ 1) or directly from the bus companies.

By Shared Taxi
There are "shared taxi" services (using Toyota Camrys - don't expect to see brand new ones) from one town to another town in Cambodia. This type of taxi is usually shared by 6-7 passengers, excluding the driver. Though it is more expensive than interstate buses, you can reach your destination faster, however it is more comfortable travelling by bus, since you will have more space for youself and more space for your belongings.
A shared taxi trip from Siem Reap to Phnom Penh takes about 4.5 hours at a cost of around 50,000 Riel, to Sihanoukville is around 30,000 Riel (about a 4 hour journey). They leave early from around 5am and the last departure is usually around 3pm. Guesthouses usually know how to get one for you, but probably you need to compare their fares and details to avoid being overcharged or misinformed.
