Ok, so there's a few huge ships out front that do a show at night. that's the biggest thing here that speaks of Treasure Island (unless you're in the casino). But otherwise, it's a very basic hotel. The rooms are nice, however, dont' get me wrong (you DO have to pay more for internet access-ACK). Check in is relatively fast, especially in comparison with the other hotels on the Strip.
Depending on the room, you can get some great views of the Strip (please know that if you're in the front of the hotel, there are 4 Siren of TI shows nightly). The bathrooms are above average, and the rooms come equipped with safes, and the decor is a bit um, poufy, shall we say (I guess they were going for the Pirates of the Caribbean)?
