I was pretty annoyed when I found out I wouldn't be able to go to the the olympic park
Was your hotel opposite the ExCel Arena? Same rates as the one I've got booked. How were the queues and the spectator zones?
My hotel is on Stratford High Street, so it's very close to Olympic Park. Only a ten minute walk away. I collected my tickets from the park box office and each one came with a free travel pass. I don't know how flexible they are or if they last the entire day but the passes are perfect for getting trains to the arena. They saved me a lot of money from travel costs.
