I'm not sure if you are familiar with the Trop. Just a reminder that the Island Tower is long way from nowhere. It's the desired rooms if you have a car and don't valet, and still isn't a short walk. The Island rooms are newer but I think the Paradise rooms are recently remodeled. I thought the Island rooms were brighter and more modern. I thought the Paradise rooms had that old Vegas dark wood feeling, although I haven't seen the remodel job. Personally, I like the suites of the old Las Vegas because they were nice. Many newer suites are just adjoining rooms.
I'd call it a 50/50 toss up, leaning to the Paradise for the convenient location.
