Every South East Asian country which has a King (in power or not) has the Grand Palace. Ex: Kingdom of Cambodia, Kingdom of Thailand. And following the Oriental pagoda style is the Grand Palace in Phnom Penh, the capital of Cambodia. Located conveniently in the heart of Phnom Penh, in the vicinity of the river promenade and shopping center, the Grand Palace has a huge entry fee of 6.25 USD (payable in USD). It has it fair share of visitors everyday and several pagodas housing age old Royal possessions. A good touristy sight.
It is well maintained and worth a visit if you have a single day/ two day itinerary in Phnom Penh.
Getting around: Hire a tuk-tuk for the whole day. They usually know the spots people like to visit and include it in the price. We paid a good $15 for half day and am sure it costs less than $10 for the day, except you have to bargain.
Shopping: Cambodia's biggest industry is clothing. Buy any piece of clothing, branded or unbranded, bargain a lot., surely it is a steal compared to the malls selling "Made in Cambodia" clothing back home
