I envy you DillyGent, love going to Vegas as gambling is a passion of mine...
Won $3,000 on the "Champagne" slots, but felt like a million - I was so excited!!
If you play roulette your on your own, (so to speak), but if you play blackjack - depending on where you sit - you can be intimidated by the other punters as your next move can influence their play of cards. Best to stand back and watch a few games first, to get the mood of play...
I used to play roulette quite a lot in London, but my favourite was craps, until it was scrapped (licence costs), but never played it in Vegas....maybe one day tho!!
Enjoy your trip !!
