Hello jennyn,
And welcome to TalkVegas!
May is a lovely time of year to visit Las Vegas. However it is a holiday weekend here in the States (Memoriel Day, Monday May 26). So as Daisy mentioned, the first 2 nights of your stay may be a little on the high side, as many Californians (large state next to Nevada) take advantage of the 3 day weekend and drive over to Las Vegas.
I normally visit Vegas during this time of year each year, so I know exactly what's going on. After Monday Afternoon, things thin out, as they head back home. From then on out, it's usually rather quiet. The one good thing about the larger crowds on the first weekend is, normally there is top entertainment for the weekend.
The only problem I see with your travel dates is you have a Saturday arrival planned. A great many Hotel/Casino's won't allow a Saturday arrival, and on a 3 day weekend it may get even tougher to secure a room for that Saturday.
My advice is to start looking now, and if something looks good to you, take it. As your travel time gets closer, and room space gets limited, that Saturday arrival, may become a problem.
12 years? WoW, I would love to know what you think of the place after your visit. So many things have changed. The city just never stands still.
Again...Welcome to TalkVegas, any thing we can answer for you, just feel free to post away!
