I didn't spend much time on the strip last trip and didn't get inside the Linq at all but, as I recall, the casino is a little on the smallish side but they did have a pretty fair variety the last time I played there. I only play slots so I can't speak toward their table games if that's what interests you. It's right in between Harrah's and Flamingo, though, and it's very convenient to other casinos as well.
Well, I sure hope Boyd isn't tightening up the comps because they're the only ones who show me any love these days. I've been getting 3 free nights at the Fremont for a couple of years now (They even started adding $10 slot dollars and $20 food credit. Hey, Big Spender!) and Gold Coast has been offering me 3 nights and a slot tournament entry for $90. I doubt that would make even the lowest rollers swoon but it's more than anyone else is offering.
My offers, both mailer and online, are only showing up through October at this point. I'm probably going in November so here's hoping they don't quit on me now.
I haven't tried the suggestion of putting in nights under booking and seeing what pops up. I miss the old way where you could see a month and the prices at a glance. I generally choose my dates off a combination of when I can find both airfare and room prices that don't give me the vapors. It makes the process a lot easier when I can look at a whole month's worth of rates rather than feeding in a bunch of dates to see what comes up.
I've stayed at all of them except Harrah's, who I've avoided because they had this bizarro set up where the AC was motion-activated. Bonnie just stayed there recently and said that they've come to their senses and now the AC works like AC is supposed to, at least in the most recently renovated tower. I'm not sure if the other tower is still on the old system or not. If it's not, that's a deal-breaker for me. The location is great and lots of food options.
Out of the others, I really liked the rooms at Bally's. Their standard room is bigger than anyone else's that I've seen and they're pretty cooperative with any requests. Minuses are that it's a fairly hefty walk from the casino to the strip and I'm not that keen on their food choices. Your mileage may vary on that and it is connected to Paris which has options I like.
I've only stayed at Flamingo once. They wouldn't let me into my room until about 6:30 and the room hadn't been touched. Bed unmade, trash overflowing, and wet towels all over the floor. They did send someone up right away and the rest of my stay was fine but it wasn't a good first impression. That said, I did like the room a lot and the location is good.
Out of these, I'd probably pick the LINQ. The rooms are on the small side but it's just me so that didn't matter. A huge plus to me was that all rooms come with a mini-fridge. The location is great. There are a lot of food options, plus one side opens to the Promenade which has a lot of cool shops and eateries. Flamingo also opens to the Promenade.
