Dole may actually think twice about taking the sponsorship deal as things stand right now. As they stand at WDW, the Dole stand is basically the first thing you come to when you cross the bridge from the hub into Adventureland. They have one of the most prime locations in the park, and when the line gets long there it almost creates a bottleneck where people will stop and say "Hey, what are all these folks standing in line for, wow, those ice cream things look awesome, I want one!" I mean, I know that before I had kids of my own, the Dole stand was always the first thing I did on my trip. Stroll down Main Street, bust a left at the Hub, chow on some Dole snacks.
If they were to take a spot at the Tiki Room, they'd most likely lose that prime location. Now, of course, one could argue that the location right there at the corner of the current Tiki Room, across from Jungle Cruise and next to the Magic Carpets, just down from the Pirates would be a very prime location as well, so it may be a moot point. It was just the first thing that popped into my mind when I thought of Dole agreeing to relocate.
That being said, one of the big current draws of the Tiki Room is a nice air conditioned spot to sit and relax on a hot day. If you could also enjoy a tasty Dole Whip while taking that break, in my mind it would be a big win.
Personally, I still love the idea that was Walt's original idea, being a dinner show. It probably is not ever going to happen now, since I am pretty sure the Be Our Guest restaurant is going to do the kinds of things that Walt had originally envisioned for Tiki at DL. I just know that I'd have it first on my ADR list every trip if I could enjoy the atmosphere and music of the original Tiki room while having some Hawaiian / Polynesean style grub. Serve me some Spam over white rice covered in brown gravy, with a side of macaroni salad, let me Sing like the Birdies Sing, and I'd be a happy camper.
