About the babysitter .... Analisa also stated on NG that EJ wanted her to babysit Gabriel at her own house, which was very very bizarre since EJ was only gone about 2 hours and it made absolute sense to babysit at the hotel.

The only explanation I can think of for Elizabeth wanting the babysitter to watch Gabriel at the babysitter's house is that Elizabeth needed the hotel room for something else.
If what the babysitter said is to be believed, Elizabeth was dressed "sexy", in a short skirt, and very short, tiny top (the exact description fails me).
Also, that Elizabeth was in a sour mood, and in a hurry to leave (which makes me think she was in a hurry because she was meeting someone), and returned in a very good mood, after only two hours.
I think Elizabeth wanted Gabriel watched elsewhere because she wanted to 'entertain' someone in the hotel room- possibly for money, possibly for drugs (cocaine or meth can put someone in a good mood in a hurry- hell to come down from afterwards, though), definitely for sex. Probably someone she met through Craigslist or something similar- which I'm sure she had access to on her phone.
You can't very well entertain a man in a hotel room with a cranky, sick baby and a babysitter sitting right there.
