I am new to priceline (and hotwire) and was hoping to get some advice on the best way/time to "bid" for hotel spots as well as an appropriate bid amount (I realize that these aren't guarantees but any general advice would be great). My girlfriend and I are planning to spend two nights in Athens, Greece (July 16-18) and would like to take advantage of the low prices to stay in a 5-star hotel. Since we are only in Athens for a short period of time, we would like to stay close to the acropolis, temple of Zeus, etc. We recently found a Hotel called Royal Olympic Hotel that books rooms at $113/night (our goal would be to get the room for $90-100/night, unless that is unreasonable?). It is located in the Syntagma Square region and, it looks to me that it is the only 5-star priceline hotel in this region. I was thinking of making a bid for this region only, with the hopes that an accepted bid would be at the Royal Olympic Hotel. That being said, we would be happy at any 5-star hotel within that region (as the proximity to the center of Athens is the valuable part), so I thought this might be a good time to try Priceline, since it is probably a bad idea to be dead set on a hotel when it is not a guarantee. Any advice, suggestions, or comments about whether this will or will not work (or be worthwhile) are welcome!
