I think the clubhouse that Pedro refers to is the one for the villas/owners which is at the new end of the resort, rather than a golf clubhouse which is by the hotel. Either way, there's a shuttle although you're not that far away anyway (bear in mind us Brits like to walk a lot!).
We own at WMH and really like the place. Mrs D highly recommends the Spa and I'd recommend the golf. Give the Gary Player course a go too (a few minutes drive away).
We definitely prefer the 2nd-floor properties and, as Pedro suggests, ask for golf course view. The pools are good although we've never stayed during March/April before. Usually we visit in late May/early June when it's a) hotter and b) quieter.
The only point against WMH, for us, is the dining. It skips from bar snacks straight up to what we view as v.expensive. The quality is good but we now prefer to take a drive, either into Palm Springs or the closer option around The River and El Paseo. The concierge at WMH is usually good at providing recommendations.
Have a great trip, we've got to wait another five months yet!
