Hiya all,
I forgot to update this after I got back!
I'm now back out in Las Vegas later on this morning and remembered the advice here- so thanks to all who responded, much appreciated!
I got to see 60% of Vegas in amongst being super busy, stayed at the Stratospere which I found to be excellent for paying what turned out to be the equivalent of £36/night. Had a hire car, super easy to get around too. Drove up and down the strip many times for just pleasure as well as getting supplies, meeting with other business associates , sightseeing! no chance to do the Grand Canyon or Hoover Dam etc, time was short for that. I was also a 'very good' boy and didn't get plastered on any evenings, I didn't go to any naughty shows, and I set my gamble limit to $100 - which went on a slot machine I actually understood ! (read the simple 1 Dollar one!) - I don't understand the craps/poker tables at all - so I just stood at one pretending I knew what was going on so I could also pretend I 'actually' was in 'Casino' ! after about 45 seconds I felt like a plonker so wandered off - that requirement all 'done' !
I'm flying later on today, back there for the next week or so, then a couple days in LA then over to Cinncy for 5 days or so. All business so very little time for relaxing

I'll get a bit of leisure time in though! Thanks all for your advice and suggestions - when I do get some more time, I'll probably do Vegas 'properly'
