Imyh going on the AC glitch to Israel for Purim, returning Monday morning.Besides staying in Kfar chabad, is there any hotel (prefer a points hotel) near a men's mikva + minyan for shacharis within reasonable distance to TLV (for Monday morning)?
Maybe you can airbnb near the Yeshiva in Ramat Aviv? They probably have a few shachris minyanim, and a men's mikvah on premises.
sheraton has a nice shul 4 minutes away on ben yehuda and smolenskin
If your willing to travel a bit, Bnei Brak is not to far.
