I already did my review and enjoyed my stay but got a bigger than expected bill on my credit card- turns out you add $100 per day on the credit card until its all sorted out-I think that should have been disclosed and I should have taken a written receipt- did not get the email receipt-it took 4 calls and quite a bit of waiting and being put on hold to figure out all this-the stay was great but full disclosure please- thank you
