For Chichen itza, you mean you joined the local tour to get there?
Actually, I will get there at afternoon..take photos and get in..and wait till 7pm and take the night view and go back..You mean it will close at 5pm, but I could still take photos outside, right?
See
http://www.cancunfuntours.com/chichen4.htm , but I don't know whether there is only night view on Wednesday.
Is it much cheaper to go alone than joining local tour?? since I have a bit more time..
One thing I concern is the bus to return at night as I mentioned above..
Hope you could give me some advice...I am sorry that there are so many questions..
Thank you very very much!!!!!! =]
