We've stayed at the Trop a couple of times; however, its probably been 5 or so years now.
The pool is great and usually opens up on April 1.
The rooms:
Older garden level -- okay, nothing to write home about
Towers -- Nice
Normally you don't spend much time in your room so I would say "go for it." The Trop is in just about the best location you could hope for in that you have several major hotels (Mandalay Bay, Luxor, Excaliber, NY NY, Monte Carlo and MGM) all within an easy walk/tram ... Monte Carlo has a tram to the Belagio and I believe the MGM has one to Bally's. This is actually the section of the Strip that we hang out the most in.
The Trop has the best and least expensive comedy club too ... well worth the money!!!
p.s. We've spent quite a bit of time in LV because my sister and her family live there ... we were just there over the holidays so if you have any other questions, just ask!
