The Activity Club and the Ice Dungeon Challenge

Isabel and Ed walk over to the nutcracker by the blocks. There are several rows of blocks with letters on them. The first letter of each word (indicated by a [ ]) is red, and the rest of the word's letters are green. The blocks are in the following order:

[A]ustralia
[R]ussia
[O]rlando
[U]ruguay
[N]ew Orleans
[D]enver

[T]exas
[H]onduras
[E]urope

[W]arsaw

A plaque on the wall behind the blocks reads:
"You're taking a trip AROUND THE WORLD. Name four places you can go next, in order! The nutcrackers buttons will light up for every correct answer."

Sounds like a tough riddle, but Isabel and Ed know they can solve it. Which of the following places could they go first?
