I have never given them my home address or phone number. Use the link on the home page, request your dates, give an email addy where they can respond to and hit enter. You will get an email telling you what's available for those dates. You can then accept and confirm or walk away. No cc info is required ahead of time, or at all if you pay cash. 2000 baht deposit up front refundable upon checkout minus anything used from the mini bar. You pay on checkout and, again, no cc is required ahead of time so if you pay cash no worries. I used my visa card with no problems.
I like this place obviously but they do take good care of you. You are thirty seconds from Walking Street so if none of the ladies strike your fancy there are hundreds, if not thousands, mere moments away. They are girl friendly and you can bring as many as you can fit in the room. No tub but the shower is easily able to handle social occasions. I have not brought any girls in from outside into the bar but people I've talked to say there is no problem doing so and the girls are treated politely. Royal Garden Plaza, Central Mall, Mike Shopping and Tukom are all minutes away by baht bus, as is Soi Diana, or if you feel in the mood to stroll you can do that too. There is a decent massage place half dozen steps from the hotel or bar doors. Excellent foot, oil and Thai massage and at least one of the girls will do extras. They will also come to your room. I used the taxi service but yes, it is a bit steep. I like the convenience of walking out from customs and finding my driver mere steps away.
