Unsure if this is already mentioned, I've had a quick scan of a couple of pages.
Best value comps for $1k and under? Rio Daily Deepstack (with insane variance), or there is a spready with all the Vegas tournys on, usually Golden Nugget and Binions will have $200ish tournies most days with much less variance. Pretend the buyin was $300 and get a proper hotel room with the change.
Good hotels near or on strip that don't cost world? - Inc gym, attempt at a semi healthy schedule is imminent. Stay somewhere fairly centrally on the strip for your first visit. If you look hard enough, you'll find a really nice hotel for your exact dates for less than a shit-tip of a hotel that someone else recommends "because it is cheap"
poker player room rate tips? Most will have the qualifying conditions and rates on their website. Usually 6 hours per day cash games, or a decent sized daily mtt buyin. This can range from very good value, to volunteering for 6 hours servitude each day whilst paying a higher rate than was available via promo code with no obligation. But often, (i.e. Venetian
http://www.venetian.com/casino/poker-room/suite-rates.html) it is a pretty good deal, but not such a slam dunk that you shouldn't try and beat it.
Best attractions for 2015? You'd have to give more info in what you are looking for. Best way in Vegas is don't be lazy, each day pick off 3-4 hotels and go explore them.
Best days out for 2015? Boat on Lake Mead. Waterpark. Mt Charleston or Red Rock trail for a change of pace. A pint in every casino downtown
Anything people would advise a Vegas virgin absolutely doesn't miss? Bellagio Fountains. Caesars or Cosmo buffet. Swanky steakhouse. Tasting menu in Picasso. Some form of Cirque du Soleil show, too.
Pool parties anyone recommends? Wet Republic (MGM) and whatever the name of the one at Encore was.
Best club? Ask someone under 40
$$$ to sell? Depends when you are going, if late, then there will be some for sale on here. You can work out how many you are taking, how much that would save you, and whether or not it is big enough difference to bother picking them up.
Public transportation in vegas??? It probably costs you £200 a day to be in Vegas for a week, direct flight and nice hotel. It seems pretty pointless spending £50 (the quarter of a waking day you'll spend fannying around on a bus) get in a taxi or hire a car and spend more of the day doing things, rather than getting there!
