Translation of portion in Spanish

The entrance hall where the passports were checked was renovated and had many ads for products from Western countries. Once we passed it and picked up our luggage we were looking for a ride into the city.
Due to jet lag (for us it was 10p.m.) we could not sleep, so we stayed at the airport until the morning where we had to take a flight around 8a.m. The destination was Siem Reap in Cambodia.
We first took a regular bus to the border, which was basically just an empty building. There we switched to Jeeps, as the terrain was rocky. In our group there were 4 American girls and us.
