Ok, just ran through the options again and then Priceline, instead of denying me, offered me a 'second bid' at 150.00 per night. I took it. I looked again for re-bid zones, but I didn't see them - not sure what I was missing, but I'll give it closer inspection next time. So, I've ended up at the Holiday Inn London Mayfair for 4.7 and 4.8 - not my first choice and about 25.00 more than I wanted to spend BUT, I'm ok with it. I think the royal wedding later that month is a factor and I'm happy to know I have a reservation. Thanks so much for your help and I was able to book with the PRICELINE links here! cheers, hayes
