Two different Vegas bachelor parties: In the first, the group stayed at Bally's in March...during the second weekend of March Madness college basketball (sweet sixteen, elite eight). We placed some bets at their big Sports Book and rented out cabanas by their pool. The cabanas were very comfortable, well stocked, and we got good drink service -- great for keeping the bachelor rolling...Bally's is a solid option for those who are looking for value and convenience in their accommodations.
The other bachelor party, the group I was with stayed at Mandalay Bay in April. March and April in Vegas, the weather is perfect...comfortably warm. Mandalay Bay has nice rooms, is very convenient from the airport, and I found the rates very reasonable. The pool was beautifully done.
