Did this and stayed at that place. It isn't chabad though (even if the rabbi is lubavitch). Hotel pushed both ways, but I had to remind them once by walking to the front desk.
There is a way into the hotel without having to worry about an automatic door, btw. The garage has an unlocked door on the second level that connects to the main hotel staircase - which lets you access the lobby or guest floors without triggering anything.
Thanks.
Already went and returned. Ended up having someone from the shul push the baby but I didn't like it at all.
In any case the rabbis are Lubavitch and wonderful people. We ate by one of the Shluchim Friday night and had an amazing meal. They are such a warm welcoming family with beautiful well behaved children.
The Shul itself belongs to the local community that isn't lubavitch. The shul was donated by some guy a bunch of years ago and includes a whole complex with a shul, dining hall, kitchen, some living quarters etc.
On Shabbos morning after davening they have a large community Shabbos meal for free and the entire community and any guests are invited. The food was amazing with many types of dishes and lots of quantity. The tables are set very nicely with real dishes and silverware and the meal is handled by waiter service. We especially relished the opportunity to meet and converse with many people from the local community and get a "real" feel of the place and people.
