Last trip we stayed 4 nights in 3 hotels which was a bit much but really liked the variety., Staying another four nights and want to do just one night in a different hotel. Aria would give us nice access to well....Aria but also quick access to Cosmo, Bellagio and Park MGM. Mirage would give us access to Mirage and TI and others in that area. No interest in the pool. Looking for a basic room or maybe one possibly two levels up from basic. Between Mirage and Aria, which would you choose and why? Also, which room?
