Looking for a LNF rate for any centrally located London Marriott (2/01/09 - 2/04/09 2 people/2 beds)- we're going for pleasure but arriving on a Sunday and leaving on Wednesday and seems to give us high business type rates. Thought I had a great deal on the Marble Arch (Marriott website 200+GBP w/breakfast/?????? 327GBP for the 3 nights....but upon submitting my claim Marriott said it was unacceptable because they used a voucher system......I'm not familiar with why this is unacceptable.) Anyway - am looking for as inexpensive as I can get as my daughter and I are going to celebrate memorable birthdays! Thanks in advance to any super sleuths who can help.
