The issue with the Trump is that it is technically off-strip and that puts off loads of people.
If you are happy to take taxis in LAS most of the time and want to avoid casino in your own hotel then its fine. It is a short walk to the far end of the Fashion Show Mall. Personally, I would regard Fashion Show Mall and the Wynn as being at the end of the main strip. My objections to taxis is not the cost but the traffic on the strip. The traffic is cause of cars trying to turn into hotels but the traffic lights allow pedestrians crossing to take precedence. It is really a silly system coming form the UK. New York traffic is caused for the same reason.
Most people would prefer to stay on the main strip as it is an easy walk from hotel to hotel.
